Hi,

I'm new to R and would like to know, how one can populate the list with array data. 
I'm reading a tab separated table in R. The data in the table looks something like this.

#Table Data
Comp    A    B    C
Extracellular    103    268    535759
Nucleus    45603    47783    442744

#R code
myData <- read.table("table.data",
                header=T,
                sep="\t",
                comment.char = "#"
                );
inp <- scan("table.data", what=list(comp=" ", A="", B="", C=""));
n <- c(0:length(inp$comp));
myList=list();
for(i in n-1)
{
    obj <-c(as.numeric(myData$A[i]),as.numeric(myData$B[i]),as.numeric(myData$C[i]));
    
}

Need help to know if there is any function in R to push obj to myList
    
Thanks in advance for your help.
    
regards

Hello,

I contact you after having unsuccessfully asked my question to R mailing list. 

I use the package RODBC to connect to a MS-SQL server. 
I am able to getQuery from the database.

I
am now studying the sqlSave some data into the database. Unfortunetly,
I meet some issues relating to the format of the data that arrives into
the database. I have three columns. The first one should be in the
MS-SQL format "datetime". The second one in the MS-SQL format
"varchar(50)", and the third one in the MS-SQl format "numeric(20,8)".




I use the following command line:
> sqlSave(channel, DF, tablename="essai_global", rownames=FALSE, oldstyle=FALSE)

The data is indeed send to the database. But the types are wrong (varchar(255) pour les trois colonnes.)

I have then tried to use the varTypes argument, but I do not manage to use it.

If I use the following command lines:
> varTypes=c("datetime","varchar(50)","numeric(20,8)")
> sqlSave(channel, DF, tablename="essai_global", rownames=FALSE, oldstyle=FALSE)



I have the following resturn:

Warning message:
In sqlSave(channel, DF, tablename = "essai_global", rownames = FALSE,  :
  argument 'varTypes' has no names and will be ignored



and the types are still wrong..

How can I use the varTypes??? I have read the documentation, but I dd not manage to find out.

Thank you very much

Wapita

Hi,

On windows, you can use a COM client (with packages like rcom or RDCOMClient) to control powerpoint from R and insert the generated image using powerpoint's object model. You can either use the clipboard or an intermediate image file saved to disk.

Not hard to do, but this seems to be already implemented in package RPPT recently released to CRAN, so have a look at it: http://stat.ethz.ch/CRAN/web/packages/R2PPT/index.html

About the image format, using windows metafiles allows you to double-click the image in powerpoint, "ungroup", and then edit each of its components (text, lines, etc.)

Regards,

Enrique

Subject: [R] stats::decompose - Problem finding seasonal component
    without trend
To: r-help@r-project.org
Message-ID: <24389771.post@talk.nabble.com>
Content-Type: text/plain; charset=us-ascii



Hi R-help,

I'd like to extract the seasonal component of a short timeseries, and was
hoping to use stats::decompose.  I don't want to decompose the 'trend'
component so I thought I should call decompose(x,filter=0). I think I've
either misunderstood the filter argument or come upon a bug/feature in
decompose.

# EXAMPLE
x<-ts(c(2:12,rep(1,12),1:12),start=c(2009,2),frequency=12);x  # Starts in
Feb

#     Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
#2009       2   3   4   5   6   7   8   9  10  11  12
#2010   1   1   1   1   1   1   1   1   1   1   1   1
#2011   1   2   3   4   5   6   7   8   9  10  11  12

decompose(x) #ok, got some answer for seasonal component, but I don't want
to split the residual into trend and random.

decompose(x,filter=0) #this seems broken, ignoring some of the data in
seasonal calculation, and losing some points in the random component
# END EXAMPLE

I've debug-stepped through decompose and, as far as I can understand the
manipulation, it appears to ignore the first and last period. And only the
middle 12 points (all 1 in my example) are used in the calculation of the
seasonal averages. Unrelated, but it also seems to duplicate one value
during the calculation, and throw a warning due to a seemingly unnecessary
'end' argument to window.

I can probably get away with using some function like sweep or scale
instead, but please let me know if I'm just misusing decompose.  If it's a
bug, I hope the above helps..

Regards,
Mike

P.S.

I see this comment in the R 2.8.0 release notes:

 o   HoltWinters() and decompose() use a (statistically) more
        efficient computation for seasonal fits (they used to waste

Hi list,
By the entire last 2 weeks I was looking for a way to directly import xlsx
files to R in a Linux OS (Ubuntu 9.04). I already read the R Import/Export
guide, and I know how to use gdata to import xls files and read.table to
import .csv. My problem is that all data that I receive is in the xlsx
format, and I have to convert all the files to xls.
Well, when I was using Windows Vista OS, RODBC did the trick with the
odbcConnectExcel2007 function (which I know is not present in the Linux
RODBC package, probably due to drivers issue). Isn't there a way to import
this xlsx files directly to R without any previous conversion (.csv or
..xls)?

Thank you for the attention, it's probable that some one already asked it. I
even remember seen that somewhere, but without a definitive answer.

Rodrigo.

Try this: set the timezone to what you want before plotting:

You need to read up on levels() of factors; in both cases, the
ordering is determined by the levels, which are by default ordered
lexically for character vectors, but can be specified manually, e.g.

factor(Activity, levels = rev(sort(unique(Activity)))

For the first question, there is a shortcut to reorder levels of
conditioning variables:

p <- barchart(Activity ~ Percent | Stage + Colony, data = Percent.df, ...)
p[, c(2, 3, 1)]

Dear All,

First of all I would like to say I do not have much knowledge about this
subject, so most of you can find it really easy. I am doing a linear
regression and I want to test if the slope of the curve is 0. R gives the
summary statistics:

Call:
lm(formula = x ~ s)

Residuals:
      Min        1Q    Median        3Q       Max
-0.025096 -0.020316 -0.001203  0.011658  0.044970

Coefficients:
             Estimate Std. Error t value Pr(>|t|)
(Intercept)  0.005567   0.016950   0.328    0.750
s           -0.001599   0..002499  -0.640    0.538

Residual standard error: 0.02621 on 9 degrees of freedom
Multiple R-squared: 0.04352,    Adjusted R-squared: -0.06276
F-statistic: 0.4095 on 1 and 9 DF,  p-value: 0.5382

what is this t-value for? The explanation in the help file was unfortunately
not clear to me. How can I test my hypotheses that if the slope is 0?

Thank you in advance,

Evrim

you are computing a 10-dimensional distribution function at a
a 10-dimensional point; so you get a single number out -- this is
as expected.

I presume that  actually you want to compute a 1-dimensional
distribution at 10 different points, which is achieved by

Jim,
   It wasn't exactly what I was looking for but I think the ideas plus
a bit of off-list help from another member helped me get much closer.
The idea of using match is very helpful in my case because I'm able to
leverage the fact that in my data files everything to the right is
also an observation to easily create  list to the end of the row. Try
the following:

X<-data.frame(A=1:10, B=0, C=1, Ob1=1:10, Ob2=2:11, Ob3=3:12,Ob4=4:13,
Ob5=3:12, Ob6=2:11)

BrkPnt<-match("Ob1",names(X))
Ob_Group <- list(names(X)[BrkPnt:ncol(X)])

# Give to reshape to turn ObX into time
answerX1<- reshape(X, varying=Ob_Group, direction='long')

and at this point I can subset based on id or some other variable:

subset(answerX1, A==1)
    A B C time Ob1 id
1.1 1 0 1    1   1  1
1.2 1 0 1    2   2  1
1.3 1 0 1    3   3  1
1.4 1 0 1    4   4  1
1.5 1 0 1    5   3  1
1.6 1 0 1    6   2  1

   I *think* this is data that I can sent to matplot/qplot and get
charts that I'm interested in. I'll work on that today to verify but
it looks about right to me using this simple case:

PlotData<-subset(answerX1, A==1)
matplot(PlotData$time,PlotData$Ob1)

   I really like the match idea. The first observation should
generally be in about the first 20 columns of my files which can
potentially be thousands of columns wide. There's no reason in my case
to match every other column to the right as I already know they will
match. I can get a list of all the observations with BrkPnt:ncol(X) or
all the independent variables using 1:BrkPnt-1. I could also, if I
chose, extract a specific group of observations by matching Ob20 and
Ob40 to potentially find observations taken in a certain time period
[[elided Yahoo spam]]

   I'll put it back in a function as you did for use in my actual code.

Cheers,
Mark

Hi,



Is there a way in R to get the string which matches the expression, where
the expression is a substring of the parent string.



Lets say, I have $i <- "transcript:ENST0000112334 pid:ENSP000012345"

What I need is the string "pid:ENSP000012345" from $i using the query
"ENSP".



Appreciate your comments.

Hi,

I?m using R package RDCOMClient (http://www.omegahat.org/RDCOMClient/)
to retrieve data from MS Excel workbook. I?m using the code below to
count the number of sheets in the workbook and then loop the data from
sheets in to a list.

############# R code ###################
library(gdata)
library(RDCOMClient)

xl <- COMCreate("Excel.Application")
sh <- xl$Workbooks()$Open(normalizePath("sample_file.xls"))$Sheets()$Count()

DF.list <- list()
for (i in 1:sh) {
   DF.list[[i]] <- read.xls("sample_file.xls", sheet=i,
stringsAsFactors = FALSE)
   }
######################################

COMCreate opens Excel process and it can be seen from Windows Task
Manager. When I try to open sample_file.xls in Excel, it just flashes
in the screen and shuts down. When I kill (via task manager) the Excel
process COMCreate started, sample_file.xls will open normally.

The question is, how can I close the Excel process COMCreate started.
xl$Close() doesn?t seem to work. The same problem have been presented
in this post to R-help:
http://tolstoy.newcastle.edu.au/R/help/06/04/25990.html

The quantity 't' is the estimated value (-0.001599 for the slope 's')
divided by its estimated standard error (0.002499). Taking the values
as reported by the summary:

  t = -0.001599/0.002499 = -0.639856

which R has reported (to 3 significant figures) as -0.640

The "Pr(>|t|)" is the probability, assuming the null hypothesis that
the slope (coefficient of 's') is zero, that data could arise at random
giving rise to a t-value which, in absolute value, would exceed the
absolute value |t| = |-0.639856| = 0.639856 which you got from your
data.

The relevance of this for testing the hypothesis that the slope is 0
is that, if the slope really is 0, then large values (either way) of
the coefficient of 's' (reported by R as "Estimate") are unlikely.
So if you got a value of "Pr(>|t|)" which was small (conventionally
less that 0.05, or 0.01, etc.) then you would have a value so large
that getting a value at least as large as this if the hypothesis
were true would be unlikely. Therefore it would be more plausible
that the null hypothesis was false.

In your case, the "P-value" Pr(>|t|) = 0.538, so you would be more
likely than not to get an estimate at least as deviant from 0 as the
one you did get, if the null hypothesis were true. Hence the data do
not provide grounds for rejecting the null hypothesis.

Note that not having grounds for rejection does not mean that you
must accept it: a "non-signifcant" t-value is not proof that the
null hypothesis is true.

There is a good basic outline of the t-test in the Wikipedia article
"Student's t-test":

  http://en.wikipedia.org/wiki/Student%27s_t-test

Hoping this helps,
Ted.

Thanks but that did not work. xl$Quit() does not kill the Excel
process and sample_file.xls will not open.

I'm using Windows XP SP2 and R 2.8.1

Then, you can try this:

xl <- COMCreate("Excel.Application")
wk  <- xl$Workbooks()
sh <- wk$Open(normalizePath("sample_file.xls"))$Sheets()$Count()

wk$Close()
xl$Quit()

Thanks Henrique.

This is indeed short and quite simple compared to what I was using which
goes like...



unlist(strsplit(i,split=" "))[grep("ENSP",unlist(strsplit(i,split=" ")))]
J



Cheers,



Praveen.

Ok, fair enough. I'm still thinking of a language in which the meaning of
operators is apparent from their syntactical structure - probably need to
read more of "The R Inferno".

Here's an example that reproduces the problem, I think (though the error
message is slightly different):

> q<-list()
> q[[105]] <- as.numeric(c(0,0,1))
> q[[104]] <- as.numeric(c(1,1,1))
> q[[10]] <- as.integer(c(3,3,1))
> crossRsorted <- data.frame(i = c(105, 104,10))
> q[[ crossRsorted[,1] ]]
Error in q[[crossRsorted[, 1]]] : recursive indexing failed at level 2

Even though the list 'q' has component 105, 104, and 10, the expression q[[
crossRsorted[,1] ]] causes an error.
Why?

And why does this work:

> q[[c(105)]]
[1] 0 0 1

but not this:

> q[[c(105,104)]]
Error in q[[c(105, 104)]] : subscript out of bounds
> q[[c(105,104,10)]]
Error in q[[c(105, 104, 10)]] : recursive indexing failed at level 2

even though q[[105]], q[[104], and q[[10]] are perfectly legitimate items?

Coming back to my question, how to I express "select all i in a vector for
which q[[i]] meets some predicate, where q is a list?"

Thank you for the tip about 'str' - that's the typeof function I've been
craving. (I thought 'attributes' or 'summary' was all there was...)
The output for str in the original problem:

In my original problem, the output is:


> str(crossRsorted)
'data.frame':   15750 obs. of  5 variables:
 $ i     : num  105 104 9 8 10 9 98 97 10 8 ...
 $ j     : num  104 105 8 9 9 10 97 98 8 10 ...
 $ r     : num  -0.973 -0.973 0.764 0.764 0.744 ....

 $ pvalue: num  2.90e-86 2.90e-86 0.00 0.00 0.00 ...

and

 $ :'data.frame':       138 obs. of  1 variable:
  ..$ revisiontestpage: num [1:138] 0 0 0 0 0 0 0 0 0 0 ...

basically - a heterogeneous sparse list of NULL and data.frames of types
character, num, and int.

However - by construction - the q[[i]] for i in crossRsorted[,1] are all
non-NULL, as in my small reproducible example above.

I can't run 'sapply' over my list because sapply will also iterate over the
NULLs. I want to access only those components in list1 that occur in
df1[1,].

Its because '[[' accept only element, so you need use '[':

q[crossRsorted[,1]]

I'm running a huge number of regressions in a loop, so I tried lm.fit
for a speedup.  However, I would like to be able to calculate the
t-stats for the coefficients.

Does anyone have some functions for calculating the regression summary
stats of an lm.fit object?

Thanks,
Whit

Your best bet on Linux would be to open the Excel 2007 files using  
OpenOffice's Calc and save them to CSV files. The latest versions of 
OpenOffice will open Office 2007 files.

An alternative of course would be to see if it is reasonable for the 
providers of the files to save them in the older XLS format instead, 
or to see if they have other file formats that they can send you  
rather than using Excel at all.

There is a very preliminary Perl module in progress, that should  
eventually provide for a more efficient path:

   http://search.cpan.org/dist/Spreadsheet-XLSX/

But from what I have seen, there are enough problems with it  
(including data integrity issues), that I would not use it in  
production work.

Unfortunately, I don't believe that you have a lot of options on Linux  
at the moment.

HTH,

Marc Schwartz

This appears to be doing something different. For instance, my 'q' has 165
components, but what you suggest has 15750:
> length(q)
[1] 165
> length(q[ crossRsorted[,1] ])
[1] 15750

hardly what I want.

Meanwhile, it looks as though [[ ]] does not vectorize its arguments, it
curries them!

Note that:

> q[[c(105,104)]]
Error in q[[c(105, 104)]] : subscript out of bounds

gives the same error as:

> q[[105]][[104]]
Error in q[[105]][[104]] : subscript out of bounds

Very mysterious, though, in all fairness, explained in help("[[") where it
says:

     '[[' can be applied recursively to lists, so that if the single
     index 'i' is a vector of length 'p', 'alist[[i]]' is equivalent to
     'alist[[i1]]...[[ip]]' providing all but the final indexing
     results in a list.

which leads to square one: how to express "select all r[i] where q[[i]]
fulfills some predicate?"

I  have previously read "R Installation and Administration". I read it
again. It does not help me
The relevant paragraph is below. But I need lower level instructions. Where
can I find them.

R CMD INSTALL works in Windows to install source packages if you have the
source-code package files (option “Source Package Installation Files” in the
installer) and toolset (see The Windows
toolset<file:///C:/Program%20Files/R/R-2.9.1/doc/manual/R-admin.html#The-Windows-toolset>)
installed. Installation of binary packages must be done by install.packages
.. R CMD INSTALL --help will tell you the current options under Windows
(which differ from those on a Unix-alike): in particular there is a choice
of the types of documentation to be installed.

Try this:

library(gsubfn)
i <- "transcript:ENST0000112334 pid:ENSP000012345"
strapply(i, paste("\\w*", "ENSP", "\\w*", sep = ""), c, simplify = unlist)

This says to match any number (possibly zero) of word
characters followed by ENSP followed by more word
characters.  c just returns the match without
further processing and unlist unlists the result giving
a character vector (which otherwise would be a list).

See http://gsubfn.googlecode.com for more info.

Follow the link.  If Windows can't find tar, your toolset is installed
incorrectly.

Dear all, 



I am trying to implement Simar & Wilson's (2007) second algorithm and
have the following question: If I use a truncated regression on the m<n
observations, how do I get fitted values for all n observations, instead
of for m observations, which is what the command fitted returns; I would
need these to construct the left-truncation needed to draw n random
deviates. 



Thanks for your help, 



Fleur

Curious to know if recode can work with strings containing colons.  I

Henrique,

I figured out what q[crossRsorted[,1]] does - it produces q[i] for all i in
crossRsorted[,1]. Ok. Since a given index 'k' of q[[k]] can occur in
multiple rows in crossRsorted[,1], this is not what I want.

Meanwhile, I was able to express what I do want like so:

crossRsorted[Filter(function (idx) mean(q[[idx]], na.rm = TRUE),
unique(crossRsorted[,1])), ]

but, I'm afraid, that's not really "R style."  Or is it?  But perhaps the
only way?

I think I'm starting to see the allure of R: every indexing task ends up a
challenging puzzle.
Which prevents Alzheimer's [1].

Whit, depending upon just how much time savings you are realizing by 
using lm.fit() and not lm(), the approach to your question may vary.

Do you need all of the models, or only a subset?

If the latter, then I would narrow down your model set and re-run them  
with lm() so that you can use summary.lm() directly. That would entail  
less custom coding, which may otherwise offset any time savings from 
using lm.fit()

If the former, then there are two choices as I see them.

The first would be to restructure the object resulting from lm.fit() 
by adding the elements required to run summary.lm(). However, I would 
think that this overhead would bring you back to a point where just 
using lm() would be a better approach from a time standpoint.

The second would be to cook up a function that only provides the  
subset of results that you need from summary.lm() and then use that on  
the results of lm.fit(). Here again, there remains the question of  
just how much time are you saving using lm.fit() versus the additional  
overhead of calculating even a subset of the output.

Here is a very simple approach to a function that would get you a  
subset of the output that you would get using, for example,  
coef(summary(lm.object)). This is using a selective approach of  
copying and slightly editing code from summary.lm(). Note that there 
is other code in summary.lm() to handle weights and such, if your  
models are more complex. You would need to add that in if that is the 
case.

If you need much more summary output than this on each model, then I 
think you would be better off just using lm() and summary.lm().


# Use at your own risk...untested on more complex models  :-)

# 'x' is an lm.fit object

calc.lm.t <- function(x)
{
   Qr <- x$qr
   r <- x$residuals
   p <- x$rank
   p1 <- 1L:p
   rss <- sum(r^2)

   n <- NROW(Qr$qr)
   rdf <- n - p

   resvar <- rss/rdf
   R <- chol2inv(Qr$qr[p1, p1, drop = FALSE])
   se <- sqrt(diag(R) * resvar)

   est <- x$coefficients[Qr$pivot[p1]]
   tval <- est/se

   res <- cbind(est = est, se = se, tval = tval)
   res
}



Here is some simple example data:

set.seed(1)
y <- rnorm(100)
x <- rnorm(100)


# Get the default coefficient output using summary.lm()
 > coef(summary(lm(y ~ x)))
                  Estimate Std.. Error     t value  Pr(>|t|)
(Intercept)  0.1088521158 0.09034800  1.20480938 0.2311784
x           -0.0009323697 0.09472155 -0.00984327 0.9921663



# Now use calc.lm.t

lmf <- lm.fit(model.matrix(y ~ x), y)

 > calc.lm.t(lmf)
                       est         se        tval
(Intercept)  0.1088521158 0.09034800  1.20480938
x           -0.0009323697 0.09472155 -0.00984327



I'll leave it to you to see whether this approach may or may not be 
helpful from a time perspective.

HTH,

Marc Schwartz

Subject: [R] Two-way ANOVA gives different results using anova(lm())
    than doing it by hand

Content-Type: text/plain; charset="windows-1252"


Hey!



Could you please take a quick look at what I have done? Somehow I get wrong results using the anova(lm()) combination compared to doing a two way ANOVA by hand.



Running:



Data<-read.table("Data.txt");
g<-lm(ExM~S1*S2,Data);
anova(g);



Gives:



Analysis of Variance Table

Response: ExM
           Df Sum Sq Mean Sq F value    Pr(>F)    
S1          1 4.3679  4.3679 167.045 < 2.2e-16 ***
S2          1 0.9427  0.9427  36.053 8.236e-09 ***
S1:S2       1 0.3231  0.3231  12.357 0.0005371 ***
Residuals 212 5.5434  0.0261                      


I compared it to the work done by hand, ie calculated all the different square sums using sum() and tapply().

So I know that anova(lm()) gets the degrees of freedom equal two 1, 1, 1 and 212 when it should be 5, 5, 25 and 180. Also, the square sums are quite different ... I get 4.xx, 4.xx, 1.xx, 0.xx ... as you see, what anova(lm()) gets is different.



The data: S1 has 6 levels, so has S2. On average, each cell has 6 values, most cells have actually 6 values, and there are two of each: 5, 7, 4, 8 - so average 6.



Could you please help me, why it does not work with anova(lm())? I tried quite a few thinks found with Google, but it all gave me the same result as anova(lm()) ... 



Thanks a lot!



Lars

Hi,

I've been wondering how to write a function that will produce results
from multiple tests (eg. paired t-tests) for all or several variables
in some data frame. I'd like it to do t-test for each variable ('x')
in 'data' by 'y'. I'm stuck in here:

function(data,y) {
for (x in names(data)) {
    with(data, t.test(x~y))
}}

How to tell 'with' that 'x' and 'y' are names of columns in 'data'? Or
pass similar arguments?

I probably understand the logic why this is not working, but still
don't know how to make it work.

You need to install the toolset, and let the installer set your path.

Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Greetings!
  I am looking for advice regarding the best way to compare GAMMs. I
know other model outputs return enough information for R's AIC, ANOVA, 
etc. commands to function, but this is not the case with GAMM unless one 
specifies the gam or lme portion. I know these parts of the gamm contain 
items that will facilitate comparisons between gamms. Is it correct to 
simply use these values for this purpose? For example, the lme portion 
of the gamm returns a log liklihood value that could be used to 
calculate information criteria. However, I am wondering whether entire 
gamms be compared using this, or only the lme part.
  Maybe my thinking about the lme and gam portions of gamms is 
incorrect? If this appears to be the case, let me know! In general, if 
someone could clarify my understanding in any way it would be much 
appreciated.
Thank you very much!
Sincerely,
Paul Simonin

Don't use with.  Use t.test(data[[x]] ~ data[[y]]).

Cvandy, is this close to what you need:

Im not really sure what you mean by "Line up the first row with

Hi Paul,

Are your GAMMs Guassian (i.e. AMM) or non-Gaussian? If they are
Gaussian, then

anova(mod1$lme, mod2$lme)

gives an approximate LRT for the two models. That will also yield AIC
and BIC which might also be used for inference. Your AMM in this case is
just a linear mixed model and these usual forms of inference apply, with
the caveat that the hypothesis testing is approximate. You end up using
both the $lme and the $gam components for various aspects of model
inspection, interrogation etc, but for hypothesis testing, the lme bit
is sufficient. You can also use things like intervals(mod1$lme) to look
at confidence on the smoothing parameters. See Simon Wood's book [1]
section 6.7 for more details, and preceding sections on how the
smoothers can be formulated as a mixed model.

If your GAMMS are generalised then I'm not sure what the best approach
for comparison or hypothesis testing might be - especially as this is an
ongoing research topic for GLMMs, and also because of the method by
which GAMMs are fitted in mgcv. Simon Wood says as much in his 2006
monograph [1, page 318, section 6.6.2]. The non-Gaussian case uses
glmmPQL from package MASS, and this doesn't return a likelihood and
hence no AIC (in the same way that quasi families in glm() fits don't
return likelihoods).

So having said that, if you do have a likelihood, then you must be
fitting AMM via gamm() and the first half of my reply would seem most
appropriate.

Hi R-helpers,

I have a dataframe (called data) with trees in rows (n=100) and insect
species (n=10) in columns. My tree IDs are in a column called TREE and each
species has a column labeled SPEC1, SPEC2, SPEC3, etc...

I wish to randomize the values in my dataframe such that row and column
totals are held constant, i.e. in my randomized data each tree will have the
same number of individual insects as in the real data (constant row totals)
and each species will have the same number of individuals as in the real
data (constant column totals).

I will eventually want to do this many times, but I would appreciate help
getting started with the randomization.

Thank you, Mark Na

This appears to be doing something different. For instance, my 'q' has 165
components, but what you suggest has 15750:

[1] 15750

hardly what I want.

Meanwhile, it looks as though [[ ]] does not vectorize its arguments, it
curries them!

Note that:

> q[[c(105,104)]]
Error in q[[c(105, 104)]] : subscript out of bounds

gives the same error as:

> q[[105]][[104]]
Error in q[[105]][[104]] : subscript out of bounds

Very mysterious, though, in all fairness, explained in help("[[") where it
says:

     '[[' can be applied recursively to lists, so that if the single
     index 'i' is a vector of length 'p', 'alist[[i]]' is equivalent to
     'alist[[i1]]...[[ip]]' providing all but the final indexing
     results in a list.

which leads to square one: how to express "select all r[i] where q[[i]]
fulfills some predicate?"

Sorry, I mixed my toy example to recreate the problem with the actual data set.

The 'crossRsorted' in the toy and in the actual are different. See my
latest posting in this thread.

Its safer just to temporarily add it to your path.

Unfortunately Rtools has a find command that conflicts with
the find command in Windows so if you add the Rtools
bin directory to your path permanently then you could
find other programs stop working.  That actually happened
to me once and it took the longest time until I discovered
that Rtools was the culprit.

If you follow the advice I gave you normally won't have
that problem.

The mvrnorm function in the MASS package has an argument to force the generated data to have the exact mean/variance structure as specified which when used with a diagonal variance matrix will generate data that has a 0 (within round off error) correlation in the data.  No post processing by Gramm-Schmidt or other methods needed.  The author(s) of the function cleverly hid this feature by placing the information on the help page for the function.

What is R's equivalent to a C-like #include to incorporate external files. I
have a 2k line function that is generated and need to include it at runtime
but not manage it as a package (as it changes hourly.) Any ideas?

I did some preliminary work on xslx (and docx and pptx) files
some time ago and will hopefully finish things off by the
end of summer.  We can read these with a combination
of the Rcompression and XML package.

I have put versions of two packages (ROOXML and RExcelXML)
at

   http://www.omegahat.org/Prerelease/

(ROOXML_0.1-0.tar.gz and RExcelXML_0.1-0.tar.gz)

There are no guarantees about how they work at this point, but
the basic structures are there. I'd be happy to hear about any problems
and to try to add functionality. Given the framework, it should
be relatively easy to add support for additional cell types, etc.

Sounds like maybe you're looking for some form of Monte Carlo
experiments in R which is on my list of to-do for the next month. I
need to do something like rearrange the dates in one database as in
Monte Carlo but then rearrange all my other databases so that dates
still match up. It's just not bubbled to the top of the list yet.

I took a quick look in Google and found MCMCpack pretty quickly.
There's some documentation out there which is easy to find if it's of
interest.

Good luck and I'll be following the thread.

cheers,
Mark

I recommend that also.  Here is the SETPATH.BAT file
that I put into my Rtools directory that sets up PATH so
it can be used for building R and R packages.  I run it
from within the cmd window I will use for building
packages.  Note that it totally replaces the current value
of PATH with a new one; it does not append or prepend
entries to the existing one.  You will have to adjust the
entries for you own machine.  It is safe to add other entries
(like e:\cygwin\bin) to the end of this PATH, but you
might run into trouble putting entries at the front of PATH.

(I have a similar script to run before building packages
for S+, whose package building system uses the Microsoft
compilers and ActiveState perl but no cygwin tools.)

E:\>type e:\Rtools\SETPATH.BAT
set RTOOLS=E:\Rtools
REM RHOME is for use in this script, R_HOME will be set by R itself.
set RHOME=E:\R-svn\r-devel

set PATH=C:\WINDOWS\system32;C:\WINDOWS

set PATH=%RTOOLS%\bin;%RTOOLS%\perl\bin;%RTOOLS%\MinGW\bin;%PATH%
set PATH=%RHOME%\bin;%PATH%

set PATH=%PATH%;E:\Program Files\MiKTeX 2.7\miktex\bin

OK, it appears that the problem is the df.resid component of the biglm object.  Everything else is being updated by the update function except the df.resid piece, so it is based solely on the initial fit and the chunksize used there.  The df.resid piece is then used in the computation of the AIC and hence the differences that you see.  There could also be a difference in the p-values and confidence intervals, but at those high of numbers, the differences are smaller than can be seen at the level of rounding done.

This appears to be a bug/overlooked piece to me, Thomas is cc'd on this so he should be able to fix this.

A work around in the meantime is to do something like:

> fit$df.resid <- 10000-4

Then compute the AIC.

Also as an aside, if you change your seq to: seq(chunksize, 10000-chunksize, chunksize) then you won't get the error messages.

Hope this helps,

Hi Greg,

Many thanks for your precious time. Here is a workable code:

set.seed(1)
xx = data.frame(x1=runif(10000,0,10), x2=runif(10000,0,10), x3=runif(10000,0,10))
xx$y = 3 + xx$x1 + 2*xx$x2 + 3*xx$x3 + rnorm(10000)

chunksize = 500
fit = biglm(y~x1+x2+x3, data=xx[1:chunksize,])
for(i in seq(chunksize,10000,chunksize)) fit=update(fit, moredata=xx[(i+1):(i+chunksize),])
AIC(fit)
[1] 28956.91

And the AIC for other chunksizes:
chunksize    AIC
500          28956.91
1000        27956.91
2000        25956.91
2500        24956.91
5000        19956.91
10000        9956.91

Also I noted that the estimated coefficients are not dependent on chunksize and AIC is exactly a linear function of chunksize. So I guess it is some problem with the calculation of AIC, may be in some degree of freedom or adding some constant somewhere.

And my comments below.

Greg Snow wrote:
How many rows does xx have?
Let's look at your example for chunksize 10000, you initially fit the first 10000 observations, then the seq results in just the value 10000 which means that you do the update based on vaues 10001 through 20000, if xx only has 10000 rows, then this should give at least one error.  If xx has 20000 or more rows, then only chunksize 10000 will ever see the 20000th value, the other chunksizes will use less of the data.
Understood your point and apologize that you had to spend time going into the logic inside for loop. I definitely thought of that but my actual problem was the variation in AICs (which I was sure about), so to ignore this loop problem (temporarily), I deliberately chose the chunksizes such that the number of rows is a multiple of chunksize. I knew there is still one extra iteration happening and I checked that it was not causing any problem, the "moredata" in the last iteration will be all NA's and "update" does nothing in such a case.

For example:
Let's say chunksize=5000, even though "xx" has only 10000 rows, "fit2" and "fit3" below are exactly same.

fit1 = biglm(y~x1+x2+x3, data=xx[1:5000,])
fit2 = update(fit1, moredata=xx[5001:10000,])
fit3 = update(fit2, moredata=xx[10001:15000,])
AIC(fit1); AIC(fit2); AIC(fit3)
[1] 5018.282
[1] 19956.91
[1] 19956.91

(The AIC matches with the table above and no warnings at all)

I checked all these things before sending my first mail and dropped the idea of refining the for loop as this will save me a few lines of code and also the loop looks good and easy to understand. Moreover it is neither taking any extra run time nor producing any warnings or errors.



Also looking at the help for update.biglm, the 2nd argument is "moredata" not "data", so if the code below is the code that you actually ran, then the new data chunks are going into the "..." argument (and being ignored as that is there for future expansion and does nothing yet) and the "moredata" argument is left empty, which should also be giving an error.  For the code below, the model is only being fit to the initial chunk and never updated, so with different chunk sizes, there is different amounts of data per model.  You can check this by doing summary(fit) and looking at the sample size in the 2nd line.
My fault in writing the mail. In the actual code, I gave "update(fit, xx[(i+1):(i+chunksize),])" ,i.e., I just passed the new chunk as the 2nd argument without mentioning the argument name, which is correct, but while writing the mail I added the argument name as "data" without checking what it is.



It is easier for us to help you if you provide code that can be run by copying and pasting (we don't have xx, so we can't just run the code below, you could include a line to randomly generate an xx, or a link to where a copy of xx can be downloaded from).  It also helps if you mention any errors or warnings that you receive in the process of running your code.

Hope this helps,

Trust me, it is the same total data I am using, even the chunksizes are all equal. I also crosschecked by manually creating the chunks and updating as in example given on biglm help page.

The AIC of the biglm models is highly dependent on the size of chunks selected (example provided below). This I can somehow expect because the model error will increase with the number of chunks.

It will be helpful if you can provide your opinion for comparing different models in such cases:

 *   can I compare two models fitted with different chunksizes, or should I always use the same chunk size.

 *   although I am not going to use AIC at all in my model selection, but I think any other model parameters will also vary in the same way. Am I right?
 *   what would be the ideal chunksize? should it be the maximum possible size R and my system's RAM is able to handle?
Any comments will be helpful.


Example of AIC variation with chunksize:

I ran the following code on my data which has 10000 observations and 3 independent variables

> chunksize = 500
> fit = biglm(y~x1+x2+x3, data=xx[1:chunksize,])
> for(i in seq(chunksize,10000,chunksize)) fit=update(fit, data=xx[(i+1):(i+chunksize),])
> AIC(fit)
[1] 30647.79

Here are the AIC for other chunksizes:
chunksize    AIC
500          30647.79
1000        29647.79
2000        27647.79
2500        26647.79
5000        21647.79
10000      11647.79

Hi Sir,

Thanks for making package available to us. I am facing few problems if you can give some hints:

Problem-1:
The model summary and residual deviance matched (in the mail below) but I didn't understand why AIC is still different.




AIC(m1)
[1] 532965




AIC(m1big_longer)
[1] 101442.9

That's because AIC.default uses the unnormalized loglikelihood and AIC.biglm uses the deviance.  Only differences in AIC between models are meaningful, not individual values.





Problem-2:
chunksize argument is there in bigglm but not in biglm, consequently, udate..biglm is there, but not update.bigglm
Is my observation correct? If yes, why is this difference?

Because update.bigglm is impossible.

Fitting a glm requires iteration, which means that it requires multiple passes through the data. Fitting a linear model requires only a single pass. update.biglm can take a fitted or partially fitted biglm and add more data. To do the same thing for a bigglm you would need to start over again from the beginning of the data set.

To fit a glm, you need to specify a data source that bigglm() can iterate over.  You do this with a function that can be called repeatedly to return the next chunk of data.

I don't know why the AIC is different, but remember that there are multiple definitions for AIC (generally differing in the constant added) and it may just be a difference in the constant, or it could be that you have not fit the whole dataset (based on your other question).

For an lm model biglm only needs to make a single pass through the data.  This was the first function written for the package and the update mechanism was an easy way to write the function (and still works well).

The bigglm function came later and the models other than Gaussian require multiple passes through the data so instead of the update mechanism that biglm uses, bigglm requires the data argument to be a function that returns the next chunk of data and can restart to the beginning of the dataset.

Also note that the bigglm function usually only does a few passes through the data, usually this is good enough, but in some cases you may need to increase the number of passes.

Hope this helps,

I have two dataframes, the first column of each dataframe is a unique id

I would like to figure out how many times each id number appears in each

So far I can use:

but this only works on each row of dataframe A one-at-a-time.  

I would like to do this for all of the rows in dataframe A, and then put the
results in a new variable: dataframeA$count

Hi,

I am writing a script that will address columns using syntax like: 

data_set[,1] 

to extract the data from the first column of my data set, for example. This
code will be placed in a loop (where the column reference will be placed by
a variable). 

What I also need to do is extract the column NAME for a given column being
processed in the loop. The dataframe has been set so that R knows that the
top line refers to column headers. 

Can anyone help me understand how to do this?

Thanks.

Possibly something like

names(data_set)[i]

?

That's true, but there is a workaround: you can manually rename the 
find.exe in Rtools, and adjust the entry in one of the R makefiles 
(MkRules), and it will use the new name instead of "find".  The reason
you might not want to do this is you might expect find to act the way it 
does on Unix:  the Rtools basically try to make Windows look a little
bit like Unix.

I'm looking for an R function that simply recodes a quantitative  
variable into a number of classes according to specified break-points.  
  Obviously I can do this using nested ifelse() commands, but I want  
to write it into a function where I can't pre-specify the number of 
classes.  Is there an obvious way to do this?

An example to clarify: how to convert c(0,10,5,1,9,6) to  
c(1,3,2,1,3,2) by specifying "breaks"=c(2.5,7.5) - or something like  
that.

Thanks,

Richard Gunton.

Well, since we don't have Data.txt it is kind of hard for us to replicate what you have done.

Here goes a guess as to what the problem may be.

Have you told R anywhere that S1 and S2 are factors with 6 levels rather than numeric vectors? Or are you just hoping that the computer can read your mind to find out this information?  

(reading minds is one of the things that R and computers in general are not very good at yet.  I have made a note to my future self to use the TimeTravel package to send a copy of the ESP package back to my past self, but I have not received it yet).

Subject: [R] matching each row


I have two dataframes, the first column of each dataframe is a unique id
number (the rest of the columns are data variables).  
I would like to figure out how many times each id number appears in each
dataframe.  

So far I can use: 
length( match (dataframeA$unique.id[1], dataframeB$unique.id) )

but this only works on each row of dataframe A one-at-a-time.  

I would like to do this for all of the rows in dataframe A, and then put the
results in a new variable: dataframeA$count

Sorry if this question has already been answered, my search of the archives
only brought up one relevant post, and I didn't understand the answer to
it....  http://www.nabble.com/match-to20799206.html#a20799206

Here is one approach (there are others, some that are probably better, but this can get you started):

1. rearrange your data so that every insect is a single row with 2 columns: the tree id and the species (this new dataset will have as many rows as the sum of the values in the old dataset).  The reshape package may be able to help with this step (you may also need the rep function).

2. randomly permute one of the 2 columns (see ?sample).

3. restructure the permuted data back to the original (the table function may be enough here, the reshape package will give more options).

Hope this helps,

Richard,

More specifically,

x = c(0,10,5,1,9,6)

cut(x, breaks = c(-Inf, 2.5,7.5, Inf), labels = c(1, 2, 3))
#[1] 1 3 2 1 3 2

Hope that helps,

Greg

Close...   

The output I'm looking for is more like this: 

output <-
data.frame(unique.id=c(1,3,5,7,9),N.in.x=c(2,3,1,2,1),N.in.y=c(0,1,3,1,1))

The first column can be gotten using a small change to the first table line: 
table ( x [ which ( x %in% x ) ] )   ##the 3rd "x" used to be a "y"

but I can't modify it to make the second "ideal output" column, I just end
up with warnings...  




Something like this? 

  > dataframeA <- data.frame (
  +   unique.id= c(1,1,3,3,3,5,7,7, 9)
  +   , x1=rnorm(9)
  +   , x2=rnorm(9)
  +   , x3=rnorm(9)
  + )
  > dataframeB <- data.frame (
  +   unique.id= c(2,3,4,5,5,5,6,7,9,10,10)
  +   , x4=rnorm(11)
  +   , x5=rnorm(11)
  +   , x6=rnorm(11)
  + )
  > match.counts <- function ( x , y ) {
  +   out <- cbind (
  +     table ( x [ which ( x %in% y ) ] )
  +     , table ( y [ which ( y %in% x ) ] )
  +   )
  +   dimnames ( out ) [[2]] <- c ( "N in x" , "N in y" )
  +   out
  + }
  > match.counts ( dataframeA$unique.id , dataframeB$unique.id )
    N in x N in y

This may be a bit off track from the data manipulation you are
working on, but I thought I'd point out that another way to
handle this sort of data is to make a table with one measurement
per row, rather than one experiment per row.

experiment measurement value
         A           1  0.27
         A           2  0.66
         A           3  0.24
         A           4  0.55
         B           1  0.13
         B           2  0.65
         B           3  0.83
         B           4  0.41
         B           5  0.92
         B           6  0.67
         C           1  0.75
         C           2  0.97
         C           3  0.49
         C           4  0.58
         D           1  1.00
         D           2  0.71
         E           1  0.11
         E           2  0.50
         E           3  0.98
         E           4  0.07
         E           5  0.94
         E           6  0.57
         E           7  0.34
         E           8  0.21


If you wrote the output of your calculations in this way, one
value per line, it can easily be read into R as a data.frame and
handled with less need for munging.  No need to remove the
zero-padding because the zeros aren't needed in the first place.

You can subset the data with subset, as in

  test <- read.table('test.dat',header=TRUE)
  expA <- subset(test, experiment=='A')
  expB <- subset(test, experiment=='B')

so there is no need to deal with ragged/zero-padded arrays. Your
plots can be grouped automatically with lattice: 

require(lattice)
xyplot(value ~ measurement, data=test, group=experiment, type='b')
xyplot(value ~ measurement | experiment, data=test, type='b')


It is simple to do calculations by experiment using tapply.  For
example


> with(test, tapply(value, experiment, mean))
        A         B         C         D         E 
0.4300000 0.6016667 0.6975000 0.8550000 0.4650000 


> with(test, tapply(measurement, experiment, max))
A B C D E 
4 6 4 2 8

Message-ID: <002401c9fff5$d6540230$82fc0690$@edu>

Hello!

I wonder if there is a typo in detrending code of spec.pgram in spectrum.R from stats package.

One can see in the code https://svn.r-project.org/R/trunk/src/library/stats/R/spectrum.R .

I am afraid there is a typo and the code should look like

if (detrend) {
    t <- 1L:N - (N + 1)/2
      sumt2 <- N * (N^2 - 1)/12
      for (i in 1L:ncol(x))
            x[, i] <- x[, i] - mean(x[, i]) - sum((x[, i]-mean(x[,i]) * t) * t/sumt2
    }


Note x[, i]-mean(x[,i]) instead of x[,i] only as in repository. Here is a quick reference http://en.wikipedia.org/wiki/Simple_linear_regression#Estimating_the_regression_line . Note $\hat b$ there. It has not x in summation, but x-mean(x).

Perhaps, the even better solution would be resid(lm(x[,i] ~ seq(along = x[,i]))) . See http://tolstoy.newcastle.edu.au/R/help/05/01/10115.html

Hooray! I got it to work. Here is what I think happened.My hold up was that
the tar command was not working. If you recall, when I issued the command:
tar xvfz RgoogleDocs_0.2.2-src.tar.gz
cmd.exe told me it could not be found

I reran Rtools29.exe which is the Rtools setup program which offered to
change my path. However it still did not work. I went to lunch and took the
opportunity to reboot my computer.

When I retried after lunch the tar command worked and everything thereafter
worked. I think that the file C:\Program Files\R\Rtools\bin\tar.exe could
not be found earlier. I just looked back at my path and I see
that C:\Program Files\R\Rtools\bin is on the path.

RgoogleDocs 0.2-2 is amazing. I can now read data straight into a dataframe..
The fact that I am always reading from realtime data is astounding.

sheets.con = getGoogleDocsConnection(getGoogleAuth("fjbuch@gmail.com",
"password here", service = "wise"))
ts2=getWorksheets("Consents Received",sheets.con)# put the name of the
spreadsheet in the inverted commas
names(ts2)
sheetAsMatrix(ts2$Sheet1,header=TRUE, as.data.frame=TRUE, trim=TRUE)

MAGIC

Boy oh boy that process of getting source to binary was super painful. Now
that I have the package as binary I can share the whole folder with my
coworker and she is able to use RGoogleDocs. I intend to use the same
process for the other two windows machines that I use. I really do not want
to go through the same installation and path hassles all over again.

Should I post my directory containing the binary files somewhere so that
others do not have to experience pain. Does etiquette dictate that I should
post the directory to help other or does etiquette dictate that it is Duncan
Temple Lang's code and thus it his prerogative to distribute his work as he
wishes?

If I am correctly understanding what you are looking for, you could do  
something like the following:

# Create some simple data. Note that only a subset of the ID's (3:5) 
will match across the two DF's:
set.seed(1)
DF.A <- data.frame(ID = sample(1:5, 10, replace = TRUE))
DF.B <- data.frame(ID = sample(3:7, 10, replace = TRUE))

 > DF.A
    ID
1   2
2   2

Now, create counts of the IDs in each, coercing the results to data 
frames and setting the count column name for each:

TAB.A <- as.data.frame(table(DF.A$ID), responseName = "Count.A")
TAB.B <- as.data.frame(table(DF.B$ID), responseName = "Count.B")

   Var1 Count.A

2    4       3
3    5       1
4    6       4
5    7       1


Now, use merge() to join each of the two above. 'all = TRUE' will 
include non-matching keys:

 > merge(TAB.A, TAB.B, by = "Var1", all = TRUE)
   Var1 Count.A Count.B
1    1       1      NA
2    2       3      NA
3    3       1       1
4    4       2       3
5    5       3       1
6    6      NA       4
7    7      NA       1


Note that you will get NAs for any non-matching ID's (Var1).

See ?table, ?as.data.frame and ?merge for more information.

Mike,
   It's not really that far off track as I didn't have any background
when I started this in R. This is the first time I've used it. I
simply chose to use a format that I thought would work for me in both
Excel and R. I do like your examples.

   My impression of reshape coupled with cast is that it's pretty
capable of giving me more or less the same format you suggest although
it is a bit of work. Currently in my files I save only the start and
finish times of the experiments and planned on calculating all the
times in the middle if necessary. With this format I'd just write them
out on each line and save that work in R.

   I suppose the files using this alternative format would be a lot
larger on disk. I currently have 10 values + 500 observations per
experiment with an average experiment tracking file containing maybe
500-1000 experiments. With this format in the worst I suppose I'd have
(10+1) * 1000 per experiment on disk, but on average it would be less
than that because as you say I wouldn't write out any zeros. Once in R
in memory they'd be equivalent. Disk space doesn't matter but reading
and writing the files might be slower. I suppose I don't really have
to write the zeros out anyway, but at this point it's jsut one
additional subset after going through reshape.

   It might be an advantage to get to the subset commands immediately
but still I've got 10 independent variables and I suspect I'm going to
be using reshape/cast more than once to get to my answers so I haven't
been against learning how to work with it.

   Overall they are good inputs and I appreciate them. Thanks!

Cheers,
Mark

I am in the process of submitting a package to CRAN.  R CMD check ran successfully on the package on my local computer, using R version 2.1.1.  However, on the computers for CRAN (with version 2.10.0), the following errors occurred:

Warning in parse_Rd("./man/predict.Rd", encoding = "unknown") :

Are \dquote, \sideeffects, and \item not supported in newer versions of R?  Is there some underlying problem that I should fix that makes these show up?

Thank you very much.

Dear all, 



I am trying to implement Simar & Wilson's (2007) second algorithm and
have the following question: If I use a truncated regression on the m<n
observations, how do I get fitted values for all n observations, instead
of for m observations, which is what the command fitted returns; I would
need these to construct the left-truncation needed to draw n random
deviates. 



Thanks for your help,

Hi,

I am analysing gene expression data using the heatmap.2 function in R and I
was wondering what is the formula of the "raw z-score" bar which shows the
colors for each pixel.
According to that post:
https://mailman.stat.ethz.ch/pipermail/r-help/2006-September/113598.html, it
is the

(actual value - mean of the group) / standard deviation.

But, mean of which group? Mean of the gene vector? And actual value of that
gene on a sample?  I would be grateful if you could give me some more
details about it or even if there is a book/manual that I could address
to..

Thanks a lot,

Chrysanthi.

I'd like to write some objects (eg arrays) to a log file. cat() flattens them
out. I'd like them formatted as in 'print' but print only writes to stdout.
Is there a simple way to achieve this result? 

Thanks

To my mind its pretty serious that Rtools can make other
software not work and the importance of using the word
find in the tools is close to zero.  Most people never even
look at the scripts.

Why don't you just rename find.exe to find2.exe, say, in
Rtools and adjust the other files accordingly. For the small
number of people who ever look at the scripts it will be obvious
that we are dealing with a find variant and the danger and need
for kludges is eliminated.

>From an email suggestion, here are two sample datasets, and my ideal output:

dataB <-
data.frame(unique.id=c("A","B","A","B","A","C","D","A"),x=27:20,y=22:29)

## ideal output would be: 
dataA <-
data.frame(unique.id=c("A","B","C","B"),x=11:14,y=5:2,countA=c(1,2,1,2),countB=c(4,2,1,2))


so my mystery operation(s) would count the number of times the unique id
shows up in a given dataset.  
my ideal outputs are as follows: 
countA is the "mystery operation" applied to dataA (counting occurrences
within the same dataset)
countB is applied to dataB (counting occurrences within a second dataset).  



My best try so far is to do: 
tempA <- aggregate(dataA$unique.id,list(dataA$unique.id),length)

which gives me a matrix with ONE instance of each unique.id and the
counts...
(and which I thought was kinda cute)
but it only works for within a single dataset!

Subject: [R] bootstrapping error message "Error in t.star[r, ] <-
    statistic(data, i[r, ], ...) : number of items to replace is not a
    multiple of replacement length"
To: r-help@r-project.org

Hi,

I am trying to run some bootstraps with the boot package. When I run 
it with 400 replicates it does it ok, but then I need to run the same 
analysis but with 89, 86, 102 and 106 samples (for four different 
environments), and then is when I get the error message:

 > mybootstrap <- boot(Datos, mystat, 2000)
Error in t.star[r, ] <- statistic(data, i[r, ], ...) :  number of 
items to replace is not a multiple of replacement length

Anyone familiar with this error message?
Does anyone knows the minimum sample size for boot package to run 
properly? Is there anyway to tell R how many samples should it pick 
for the resampling?

If it helps, this is how my model looks like:

mymodel = lm(Datos[,4]~Datos[,1]+ 
Datos[,8]+Datos[,9]+Datos[,10]+Datos[,11]+Datos[,12])
summary(mymodel)

mystat <- function(a,b)
f<- lm(a[b,4]~a[b,1]+a[b,8]+ a[b,9]+a[b,10]+a[b,11]+a[b,12])$coef

mybootstrap <- boot(Datos, mystat, 2000)

INT1<-boot.ci(mybootstrap, conf=0.95, type="all", index=1)
INT2<-boot.ci(mybootstrap, conf=0.95, type="all", index=2)
INT3<-boot.ci(mybootstrap, conf=0.95, type="all", index=3)
INT4<-boot.ci(mybootstrap, conf=0.95, type="all", index=4)
INT5<-boot.ci(mybootstrap, conf=0.95, type="all", index=5)
INT6<-boot.ci(mybootstrap, conf=0.95, type="all", index=6)
INT7<-boot.ci(mybootstrap, conf=0.95, type="all", index=7)


Thanks for your help! I am new to bootstraps and to R, and I feel 
pretty lonely with this

You didn't read what I wrote.  It could be called anything as far as the 
scripts are concerned.  I explained to you how to rename it and keep
them happy.

I understand what you wrote. Its just that I don't agree that that
is a reasonable solution.

What is wanted is something that works safely out of the box,
not something with a built in danger that every single person
that uses it must fix (and know about it to fix) in order to
maintain the integrity of their system.

"Ind" are different individuals in the study, each of which received 
three "Treatment"s (SC, SH, and AC). The "Order" (ordered=TRUE) in 
which each individual received a treatment was systematically  
shuffled in the study, and the "Date" (ordered=TRUE) is simply when 
each treatment was completed.  The response variable are scores from  
a principal components analysis ("PC1").

So I want to run a model where "PC1" is the response variable and  
"Ind" is nested within "Treatment", and I also want to include  
"Order" and "Date" as random factors.

I have been struggling to describe the model with aov, lm, lme, and 
lmer, and don't think I'm getting the syntax right.  Suggestions?

Thanks for your time and consideration,
-Jeff

Hi,
   What is cast telling me when it says the following?

Aggregation requires fun.aggregate: length used as default

What is 'length'?

   I've taken a small subset of data and wondered what EnTime vs
ExTime might look like. cast is kind enough to give me a table but I
don't understand the values in the table. They seem to sum up ro be
the same as the total dimension of the data so I'm guessing (but
cannot prove) that it's something like whether each experiment has
values for both EnTime and ExTime?

   Assuming that cast is taking some sort of sum then I'd like to
learn how to replace the value in the table with something meaningful
to me. On thing would the the ExNum value from the first occurrence at
that crosspoint, or the PL_Pos value, etc.

   How might I write a fun.aggregate to to that?

Thanks,
Mark

As far as I know, you are the only person in the whole world who has 
been affected by this.  But fixing it would inconvenience hundreds of
people, who would have to install a new version of Rtools, if the make 
system suddenly started looking for find2 instead of find.

So it's unfortunate that Microsoft chose to use the name of the wrong 
Unix utility when they wrote find, and it's unfortunate that the first 
version of Rtools didn't fix this, but there you are:  name clashes 
happen, and sometimes you need to work around them.

<snip>

Modify my initial proposal:

countA <- as.data.frame(table(dataA$unique.id), responseName = "countA")
countB <- as.data.frame(table(dataB$unique.id), responseName = "countB")

 > countA
   Var1 countA
1    A      1
2    B      2
3    C      1

 > countB
   Var1 countB
1    A      4
2    B      2
3    C      1
4    D      1


dataA <- merge(dataA, countA, by.x = "unique.id", by.y = "Var1")
dataA <- merge(dataA, countB, by.x = "unique.id", by.y = "Var1")

 > dataA
   unique.id  x y countA countB
1         A 11 5      1      4
2         B 12 4      2      2
3         B 14 2      2      2
4         C 13 3      1      1


Note that without 'all.x = TRUE' in the merge() calls, only those 
unique.id's that are common to both datasets will be in the result. If  
you want to include unique.id's that are in A, but not in B, using  
'all.x = TRUE'.

Note also that by default, 'unique.id' will be alpha sorted in the  
output.

Subject: [R] What is cast telling me?

Hi,
   What is cast telling me when it says the following?

Aggregation requires fun.aggregate: length used as default

What is 'length'?

   I've taken a small subset of data and wondered what EnTime vs
ExTime might look like. cast is kind enough to give me a table but I
don't understand the values in the table. They seem to sum up ro be
the same as the total dimension of the data so I'm guessing (but
cannot prove) that it's something like whether each experiment has
values for both EnTime and ExTime?

   Assuming that cast is taking some sort of sum then I'd like to
learn how to replace the value in the table with something meaningful
to me. On thing would the the ExNum value from the first occurrence at
that crosspoint, or the PL_Pos value, etc.

   How might I write a fun.aggregate to to that?

Thanks,
Mark

How about looking at the code?

     if (scale == "row") {
         retval$rowMeans <- rm <- rowMeans(x, na.rm = na.rm)
         x <- sweep(x, 1, rm)
         retval$rowSDs <- sx <- apply(x, 1, sd, na.rm = na.rm)
         x <- sweep(x, 1, sx, "/")
     }
     else if (scale == "column") {
         retval$colMeans <- rm <- colMeans(x, na.rm = na.rm)
         x <- sweep(x, 2, rm)
         retval$colSDs <- sx <- apply(x, 2, sd, na.rm = na.rm)
         x <- sweep(x, 2, sx, "/")
     }

So the z-score is calculated on either the row or column (or the default 
of "none").

I don't see how you can get something saying 'raw z-score'. I get either 
'Row Z-Score' or 'Column Z-Score'. So assuming you meant Row Z-Score, 
then the rows are centered and scaled by subtracting the mean of the row 
from every value and then dividing the resulting values by the standard 
deviation of the row.

Best,

Jim

Humm...OK - so I cast it with PL_Pos which has (in this data subset) a
unique value for each experiment in this set. there are 25 experiments
and there are 25 rows so each row in the output of cast should be
unique, and indeed (although it won't survive email) there is only one
EnTime now for each experiement and the 755 vs 950 reading of 25 is
the number of 5 minute periods which is the observation rate of this
data.

25   1305    180    24   0    0    0    0    0    0    3

then I might notice that experiments that start early (<830) and
others that start late (>1130) might tend to have higher PL_Pos
values.

However I'd like to get PL_Pos into the table. Does that mean melt the
data a second time?

Thanks,
Mark

No one really knows how many people are being
affected.

Also one can minimize the impact like this:

1. In Rtools, change find.exe to find2.exe.

2. In R, create a 'find' a variable in any script using find
and at the top check for find2 and if found set the find
variable to find2 otherwise set it to find.
Then fix the script to use the find variable instead
of find.

That would work with systems having find2 or having find
so new versions of R would work with both new and old
versions of Rtools.

The only combination that would not work would be
old versions of R with new versions of the Rtools but
that is not a likely combination and even if it does
occur it would give an error so the user would know
something is wrong which is far better than the current
situation where a silent hard-to-diagnose risk that is
entered onto your system.

I am using R on unix. While in R how do I execute the unix shell commands?
Is there a way to do it? I am executing a function in R and the matrix
resulting from the function has to be passed on as an input to unix command..


Any directions will be helpful.

Thanks,

How do you retrieve the color from a GtkColorButton in rgtk2?

There seems to be a promising function gtkColorButtonGetColor

However, the function doesn't return the current color, instead it *sets* a
color that you pass to it.  The function header looks like
gtkColorButtonGetColor(color_button, color), and doesn't return anything.
That's a bit convoluted, but manageable.  I'll just create a "color", let
gtkColorButtonGetColor set it, and then read the modified value

However, you have to pass a *GdkColor* type to set "color"....  The simplest
way to create one seems to be:
color = as.GdkColor('white')

It seems I should be able to pass this color to the color button handler and
see what the selected color is.

HOWEVER, this still doesn't work.  gtkColorButtonGetColor still does not
modify the created color. >:(

require rgtk2
b<-gtkColorButtonNew()
gw <- gtkWindow(show=F)
gw$Add(b)
gw$Show()


changeColor<-function(b){
    color = as.GdkColor('white') # create a color to change
    message('initial color value')
    print(color)# print it out
    gtkColorButtonGetColor(b,color) # this function should change 'color'
    message('after gtkColorButtonGetColor()... on my machine the color is
unchanged:')
    print(color)
}

gSignalConnect(b, 'color-set',changeColor)

So your WinBUGS installation is broken.
Can you please try to reinstall?

BTW, which version of R2WinBUGS are we talking about, the most recent one?

BRugs is available from the CRAN extras repository hosted by Brian 
Ripley. Is BRugs really working on your machine? I've not heared of many 
  working Linux installations.

?system

These three functions (I'm not sure bout the real name of the second)
should allow you to get the standard output of a Unix command line.

Consider also cpturing your command output in a file (reusable...).

system() just calls the program as started from the operating system's 
command line (or under Windows without an underlying shell). That 
implies that it cannot press buttons, you can "only" specify command 
line flags, if the program you are talking about accepts these ...

Dear all, 

I am trying to implement Simar & Wilson's (2007) second algorithm and
have the following question: If I use a truncated regression on the m<n
observations, how do I get fitted values for all n observations, instead
of for m observations, which is what the command fitted returns; I would
need these to construct the left-truncation needed to draw n random
deviates. 

Thanks for your help,

Subject: [R] bootstrapping error message "Error in t.star[r, ] <-
statistic(data, i[r, ], ...) : number of items to replace is not a
multiple of replacement length"



Hi,

I am trying to run some bootstraps with the boot package. When I run 
it with 400 replicates it does it ok, but then I need to run the same 
analysis but with 89, 86, 102 and 106 samples (for four different 
environments), and then is when I get the error message:

 > mybootstrap <- boot(Datos, mystat, 2000)
Error in t.star[r, ] <- statistic(data, i[r, ], ...) :  number of 
items to replace is not a multiple of replacement length

Anyone familiar with this error message?
Does anyone knows the minimum sample size for boot package to run 
properly? Is there anyway to tell R how many samples should it pick 
for the resampling?

If it helps, this is how my model looks like:

mymodel = lm(Datos[,4]~Datos[,1]+ 
Datos[,8]+Datos[,9]+Datos[,10]+Datos[,11]+Datos[,12])
summary(mymodel)

mystat <- function(a,b)
f<- lm(a[b,4]~a[b,1]+a[b,8]+ a[b,9]+a[b,10]+a[b,11]+a[b,12])$coef

mybootstrap <- boot(Datos, mystat, 2000)

INT1<-boot.ci(mybootstrap, conf=0.95, type="all", index=1)
INT2<-boot.ci(mybootstrap, conf=0.95, type="all", index=2)
INT3<-boot.ci(mybootstrap, conf=0.95, type="all", index=3)
INT4<-boot.ci(mybootstrap, conf=0.95, type="all", index=4)
INT5<-boot.ci(mybootstrap, conf=0.95, type="all", index=5)
INT6<-boot.ci(mybootstrap, conf=0.95, type="all", index=6)
INT7<-boot.ci(mybootstrap, conf=0.95, type="all", index=7)


Thanks for your help! I am new to bootstraps and to R, and I feel 
pretty lonely with this

Uwe, thanks for helping! After some poking around, I realized that the
problem was that I had installed OpenBUGS instead of WinBUGS. I did an
additional installation of WinBUGS, which also runs fine under Wine, and now
[[elided Yahoo spam]]

To clarify: both the OpenBUGS and WinBUGS distributions run nicely under
Linux/Wine. However, despite the fact that R2WinBUGS 2.1-14 claims (in
?bugs) it can run both OpenBUGS and WinBUGS, this does not seem to be true
under Linux/Wine. Only WinBUGS currently works with R2WinBUGS, at least for
me.

(I did figure out how to use CODA export from Win/OpenBUGS and the coda
package to import into R, but it's a bit tedious...)

This is because BRugs (the interface R2WinBUGS requires for OpenBUGS) 
simply does not work under (most) non-Windows operating systems.

The difference you are experiencing is the new Rd2 parser that is more 
picky now (but also prevents to produce wrong documentation files).

If you make the code of the Rd available, someone might be able to help.

Hi,

I am currently working on reading large files into R.  My files are text
documents with four columns and around 10 million lines.
Each line is set up as:
string|integer|string|integer

I have been trying to use read.table to read in the file, but I think I am
reading too much into memory and the application quits.

I want to be able to analyze the entire text document at once.
I have thought about reading in the file, line by line, but I still want to
store all the information together.  I have also thought about writing each
line of the file to a matrix, but I cannot seem to figure it out.

Any help would be great.
Thanks,
Amy

To the Lattice expert -

I am new to the lattice package and I would like to add a curve to the 
xyplot(). I know that I need to use panel function to add it. But it doesn't work. Is there anyone can help me out on how to transfer the data into the function?

The following is my code and I would like to add lines for xx,yy


xx <- seq(0,1,length = 100);
yy <- mean(PS$theta)*(1-exp(mean(PS$k)*xx))/(1-exp(mean(PS$k)))

ts1 <- xyplot(VCFB ~ Visit , groups = ID, data = CFB_M, type = c('g','l'),strip = strip.custom(style =4), as.table=TRUE,xlab = 'Time',ylab = 'FBG CFB',main = '3mg Change from Baseline FBG',panel=function (xx,yy,...) {
        panel.xyplot(...);
        panel.lines(xx,yy,...);});

Many thanks!!

Hi,

I am trying to subset a dataset based on a filter defined by a user... 
I prompt the user for input.. resulting in a string logical expression 
("X1 < 3").

I have tried using subset, but it is looking for a logical expression, not
a character string.
I keep getting the error:  'subset' must evaluate to logical.


Example:
x <- data.frame(matrix(1:15, nrow=5, ncol=3))
filter = "X1 < 3"
subset(x, filter)


Any ideas??



Thanks much,
Tracey

To: r-help@r-project.org
Message-ID: <24398687.post@talk.nabble.com>
Content-Type: text/plain; charset=us-ascii


Hello,

I wish to perform a substitution of certain numerical values in a data
matrix with the corresponding column name. For instance, if I have a data
matrix
V1  V2  V3
2    0    1
0    1    2 
1    5    0
5    0    0 

I want to substitute the `1' and the `2' for the corresponding column name,
and make everything else `NA' like this
V1    V2    V3
V1    NA    V3
NA    V2    V3 
V1    NA    NA
NA    NA    NA 

I have done this using an explicit `for' loop, but it takes a really long
time to finish. Is there any way I can do this using `apply' or some form of
implicit looping?

Thank you for your help,

SO

?system

These three functions (I'm not sure bout the real name of the second)
should allow you to get the standard output of a Unix command line.

Consider also cpturing your command output in a file (reusable...).

the following works. i don't exactly what happens here. I guess "lm"

I am framing this as a question since I would like to know how folks 
are currently deploying the models they build in R. Say, you want to 
use the results of your model inside another application in real-time 
or on-demand, how do you do it? How do you use the decisions you get 
back from your models?

As you may know, a PMML package is available for R that allows for  
many mining model to be exported into the Predictive Model Markup  
Language. PMML is the standard way to represent models and can be  
exported from most statistical packages (including SPSS, SAS,  
KNIME, ...). Once your model is represented as a PMML file, it can  
easily be moved around. PMML allows for true interoperability. We have  
recently published an article about PMML on The R Journal. It  
basically describes the PMML language and the package itself. If you 
are interested in finding out more about PMML and how to benefit from 
this standard, please check the link below.

http://journal.r-project.org/2009-1/RJournal_2009-1_Guazzelli+et+al.pdf

We have also wrote a paper about open standards and cloud computing 
for the SIGKDD Explorations newsletter. In this paper, we describe the  
ADAPA Scoring Engine which executes PMML models and is available as a 
service on the Amazon Cloud. ADAPA can be used to deploy R models in 
real-time from anywhere in the world. I believe it represents a  
revolution in data mining since it allows for anyone that uses R to 
make effective use of predictive models at a cost of less than $1/hour.

Is there an easy way to read the value of the cells rather than the formula?So
for instance in a cell whose value was created by simply using the value
from the cell immediately to the left in the Google spreadsheet I would
prefer to get the value rather than  =RC[-1]

When one exports with Google Spreadsheets as a csv then that does not
happen.

I am using the following line of code in R
y2009<-sheetAsMatrix(ts2$y2009,header=TRUE, as.data.frame=TRUE, trim=TRUE)

Dear Olivella,
Assuming that x is your data, here is one possible way to do what you want:

t(
   apply(x, 1, function(x){
                       index <- x %in% c(1,2)
                       x[index] <- cls[index]
                       x[!index] <- NA
                       x
                       }
           )
  )

How big is the data you are dealing with?

HTH,

Jorge

complete version:
# column names
cls <- colnames(x)

# Transformation
res <- t(

When I create a sample spreadsheet with formulae in cells
and then retrieve it with RGoogleDocs, I get the values
not the formula.  So I'll need a sample spreadsheet
from which you get the formula and not the value.

I suggest you forward to the r-sig-mixed-models list, where the
question is less likely to get lost in the noise.

A few other thoughts:

* "Order" might as well be treated as fixed, you probably won't be able to
get a reliable estimate of its associated variance.

* I'm not sure that you'll be able to make very much use of the ordering of
the factors (unless you want to be extreme and treat them as continuous
covariates, i.e. fit a linear trend) in the aov/lme/lmer world.

* I would think that

lmer(PC1 ~ Treatment*Order+(1|Ind)+(1|Date),data=data)

would be a good start.

How big is the entire text file?  What is the length of an average
line?  Have you tried to use 'scan' to read in the data?  How much
memory do you have?  Are you paging?  Here was a quick test I did with
a file with about 5M lines (12|this is some text|12345|more test):

So some more details might help to evaluate what your problem is.

Took less than a minute to read it in.

Hello,

I'm running R 2.8.1 on Ubuntu Hardy. I'm trying to install tkrplot.
Using r-cran-tkrplot from the repository, I'm getting the following error:
> library(tkrplot)
Loading required package: tcltk

Loading Tcl/Tk interface ... done
Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class =

[tcl] version conflict for package "Tcl": have 8.5.0, need exactly 8.4.


Error in library(tkrplot) : .First.lib failed for 'tkrplot'

This tries to install tkrplot version 0.0.16
However, installing R2.8.1 from the repositories automatically installs
tcl8.5. In fact, if I try and remove tcl8.5 using synaptic, it also

removes R.

I also tried to install the package from source, both by using
install.packages as well as downloading source (tkrplot 0.0.18). This
fails to install.

Can someone please help. My ultimate objective is to use the

TeachingDemos package.

Maybe there is a great website out there or white paper that discusses this but again my Google skills (or lack there of) let me down.

I would like to know the best way to export several doubles from a function, where the doubles are not an array.  

Here is a contrived function similar to my needs:

multipleoutput<-function(x)
{
    squared<-x^2
    cubed<-x^3
    exponentioal<-exp(x)
    factorialVal<-factorial(x)
    
}

Thanks again for all your help.

You can return a list, vector, or any other object:  The last value is
the return value unless you do an explicit return()

I can't vouch for the best way, but here is one way, return a list of the
values

multipleoutput<-function(x)
{
    squared<-x^2
    cubed<-x^3
    exponential<-exp(x)
    factorialVal<-factorial(x)
    return(list(squared=squared, cubed=cubed, exponential=exponential,
factorialVal=factorialVal))
}

Hope this is helpful,

I'm a newbie so mine;s probably not the best but it seems to work:

multipleoutput<-function(x)
{
    answer<- c(0,0,0,0)
    MyFuncNames <- c("Squared","Cubed","Exp","Fac")
    answer$squared<-x^2
    answer$cubed<-x^3
    answer$exponential<-exp(x)
    answer$factorial<-factorial(x)
    return(answer)
}

X = c(0,0,0,0)
X
mode(X)
names(X)

MyNames = c("Squared","Cubed","Exp","Fac")
MyNames

names(X) = MyNames
X <- multipleoutput(2)

X
class(X)

dim(X)

Yeah, R is difficult to search for - I've had partial success with
rseek.org, though.

You can always do:

> multipleoutput <- function (x) { return (c(square = x^2, cube = x^3, exp = exp(x))) }

But then you'd have to call it like so:

> mapply(multipleoutput, c(0,1,2))
       [,1]     [,2]     [,3]
square    0 1.000000 4.000000
cube      0 1.000000 8.000000
exp       1 2.718282 7.389056

If you call it like so:

> multipleoutput(c(0,1,2))
 square1  square2  square3    cube1    cube2    cube3     exp1     exp2
0.000000 1.000000 4.000000 0.000000 1.000000 8.000000 1.000000 2.718282
    exp3
7.389056

then R flattens the result.  Weird.

Hi,

I was wondering if there was an R package or routines for the Dantzig

routines to do this but I was wondering if someone had ported those to
R.

Thanks,

To: r-help@r-project.org
Message-ID: <4A55459B.6000709@usask.ca>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Thank you in advance for your consideration.

I have a dataframe of 2000+ observations with repeated measures across 
approximately 300 unique individuals  An event either does or does not
happen
(1,0) and there is a suit of independent variables associated with the 
event.  A simplified representation follows:

my.df<-data.frame("id"=c("A","A","A","B","B","C","C","C", "C", "C"), 
event=c(0,0,1,0,1,0,0,1,1, 0))

_id_  _event_
A     0
A     0
A     1
B     0
B     1
C     0
C     0
C     1
C     1
C     0

I need to sample my.df to select the same number of observations with 
event = 0 as event = 1 for each unique id.
I can reshape or tapply my.df to group id and determine what sample size 
I need.  my.df.cast=

library(reshape)
my.df.melt<-melt(my.df, id="id")
my.df.cast<-cast(my.df.melt, id~value, length, fill=0)
my.df.cast

       Event
_id_      _0_   _1_
A     2     *1*
B     1     *1*
C     3     *2*

Given the above dataframe I need to randomly select (sample) from my.df 
*one* observation from my.df[my.df$id==A & my.df$event==0],  *one* from 
my.df[my.df$id==B & my.df$event==0], and* two* from my.df[my.df$id==C & 
my.df$event==0] and then rbind them to my.df[my.df$event == 1].  
However, it is impractical to individually code each case.

Alternatively if A in my.df matches A in my.df.cast  then 
sample(my.df[my.df$id == A & my.df$event == 0], size=my.df.cast[1,3], 
replace=FALSE).  I think I am close to a solution but I'm not sure how 
to code it to run through the entire dataframe.

This is how my.new.df would look:

_id event_
A     0
A     1
B     0
B     1
C     0
C     0
C     1
C     1

Thank you kindly for your help,

Eric

That's good to know.  I have attached three Rd files that gave errors (others gave identical errors).  I would love to know what is wrong with them.

I'm using 2.1.1 because that is what is installed on the Linux computer I have access to.  (I haven't bothered figuring out how to assemble a package in Windows.)

The difference you are experiencing is the new Rd2 parser that is more 
picky now (but also prevents to produce wrong documentation files).

If you make the code of the Rd available, someone might be able to help.

Using R-2.8.0 and R-2.8.1, I get behaviour like this:

R version 2.8.0 (2008-10-20)

However:

"/home/hrapgc/local/R-2.9.1/lib:/usr/local/lib:/usr/lib/gcj-4.1.2"


I'm particularly dismayed by the fact that there are now only three
parts to LD_LIBRARY_PATH, and slightly mystified by the appearance of
/usr/lib/gcj-4.1.2 in place of /usr/lib/gcj-4.1.1.  Maybe that's a red
herring since the former is a link to the latter.

I would appreciate help getting the rest of LD_LIBRARY_PATH back.  I
set it in ~/.bash_profile in case that makes a difference to the
possible cause of the phenomenon.

$ uname -r
2.6.18-92.1.22.el5

The problem doesn't seem to arise with Fedora 8 nor with Mepis 6.5.

This version runs a bit better than my last and I find it a bit more
readable, but there's a warning for whatever the first computation is
inside the function that I'd like to understand.

R respects LD_LIBRARY_PATH, see /usr/lib/R/etc/ldpaths where it
prepends its own path to any value in the environment when R is
invoked:

if test -z "${LD_LIBRARY_PATH}"; then
  LD_LIBRARY_PATH="${R_LD_LIBRARY_PATH}"
else
  LD_LIBRARY_PATH="${R_LD_LIBRARY_PATH}:${LD_LIBRARY_PATH}"
fi
export LD_LIBRARY_PATH

=====

Provide the output of

echo $LD_LIBRARY_PATH
or
env | grep LD_LIBRARY_PATH

to check that it's set correctly *BEFORE* you invoke R.

Patrick,

When I was using Fedora, several years ago I started to add any paths 
that I needed for LD_LIBRARY_PATH into /etc/ld.so.conf. Then run 'sudo  
ldconfig' to update the configuration.

I got bit by the same issue that you are seeing when using RODBC with 
Oracle. I believe that it was Prof. Ripley who suggested that I use 
the above approach and did not have any problems after that.

HTH,

Marc Schwartz

There's nothing there.  However, you might have got me onto a 
workaround.  When
I see this:


$ diff /home/hrapgc/local/R-2.8.1/etc/ldpaths
/home/hrapgc/local/R-2.9.1/etc/ldpaths
2c2
< :
${R_JAVA_LD_LIBRARY_PATH=/usr/lib/gcj-4.1.2:/home/hrapgc/Rstuff/library/asreml/libs}
---
> : ${R_JAVA_LD_LIBRARY_PATH=/usr/lib/gcj-4.1.2}


I think a little editing job will do the trick.  Presumably, that happened at
compilation time and something screwy is happening with CentOS which doesn't
happen with other OSs.

The gcj thing IS a red herring, can we assume?

Thanks

Etiquette is one thing and the license another.
Both encourage you to help others and make the
binary available to others.
And indeed,  I hope that Windows users do build binaries
for others and remove the additional work from those
who provide the software in the first place.

Having seen this thread today, I did put a binary
version of RGoogleDocs on the Omegahat repository
so

  install.packages("RGoogleDocs", repos = "http://www.omegahat.org/R")

should install it and, if I had had time earlier, saved you the hardship
of building the binary.  Sorry to do it so soon after.

?list

e.g.,

multipleoutput <- function(x) {
    answer = list()
    answer$Squ=x^2
    answer$Cub<-x^3
    answer$Exp<-exp(x)
    answer$Fac<-factorial(x)

There already have been some suggestions on how to do this the  
"normal" R way, so let's go ahead and use the "return a list" method 
(I think it's better than using the `c(squared=x^2, cubed=...)`).

Here's an interesting way to receive the assignments. Check out this 
function:

http://code.google.com/p/miscell/source/browse/rvalues/rvalues.r

With that ':=' function loaded, you could do this:

============
multipleout <- function(x) {
   list(squared=x^2, cubed=x^3, exponential=exp(x),
        factorial=factorial(x))
}

c(sq,cu,ex,fa) := multipleout(1:3)
show(sq)
[1] 1 4 9

show(cu)
[1]  1  8 27

show(ex)
[1]  2.718282  7.389056 20.085537

show(fa)
[1] 1 2 6

=============

[I can't remember how I stumbled onto this code for the ':=' function  
(I think it was from a thread on the BioC list about package updates)]

I'm not saying that you *should* do it this way, but it's kind of cool  
that you could ...

The solution below does not include the pid: string before it.
This modification works:

> strapply(i, paste("[^ ]*", "ENSP", "[^ ]*", sep = ""), c, simplify = unlist)
[1] "pid:ENSP000012345"

I am trying to understand idea for splint, but it use Fortran code.
Does anyone know how to see that Fortran code?

Is splint a not-knot spline method?

You could try something like this:

library(sqldf)
DF <- read.csv.sql("myfile.txt", sep = "|", header = FALSE)

or possibly this, which is the same except instead of
using an "in memory" database it uses an external database:

DF <- read.csv.sql("myfile.txt", sep = "|", header = FALSE, dbname = "temp.db")

In both cases it creates the database automatically and then destroys it
automatically.

You may need to adjust the arguments depending on what your data
looks like.

Since it does not use read.table underneath any limitations of
read.table would not apply.

You might want to test it out with the first few rows to get the
arguments right and then if it seems to work try it with the
full data.

Dear Duncan
On my home computer I was able to use  install.packages("RGoogleDocs", repos
= "http://www.omegahat.org/R")

But, alas it would not read the data in the spreadsheet. It went back to its
nasty ways
Error in !includeEmpty : invalid argument type

That is what I was getting with version 0.2-1.You then sent me link to 0.2-2
(in source code) which is what worked.

Is it possible that that the windows binary version you put in omegahat was
0.2-1 and not 0.2-2?

I did not know how to tell what version had been installed.

Dear Users:
I wish to save 3d scatter plots I have generated using the plot3d command in

Thank you

Hi, I hope somebody can help me with this issue: I am doing population pyramids using the barplot command, so in the left side I have male age structure and in the right side the female age structure. To plot the male age structure I put the data in negative numbers. Now, I want to change the sign in the bar plot in such way that I have no-sign numbers, both in left and right side of the graph. I have been trying all day long and I could not succed.

Thanks Jorge, this is a very good library, but I have been trying with barplot because I am doing population pyramids with confidence intervals. So, the pyramid function does not work with more than two colum matrix.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I have two matrices:

> m1 <- matrix(1,4,4)

     [,1] [,2] [,3] [,4]
[1,]    1    1    1    1
[2,]    1    1    1    1

[1,]    1    0    0
[2,]    0    1    0
[3,]    0    0    1

I want to get indicies from m2 such that they match indicies as though they came
from the lower right of m1. Here's how things work:

> ind1 <- which(m1 == 1)
> ind1
 [1]  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16
> ind2 <- which(m2 == 1)
> ind2
[1] 1 5 9


I would like ind2 to be offset so they look like indicies from the lower right
of m1:
> ind2
[1] 6 11 16

I can be done with a simple offset when using arr.ind=TRUE:
> ind2 <- which(m2 == 1, arr.ind=T) + 1
> ind2
     row col
[1,]   2   2
[2,]   3   3
[3,]   4   4

But I don't want to use this, as I eventually want to be able to do things like:

> m1[-c(ind2)] <- 0
> m1
     [,1] [,2] [,3] [,4]
[1,]    0    0    0    0
[2,]    0    1    0    0
[3,]    0    0    1    0
[4,]    0    0    0    1


Any thoughts?
Cheers,
Nathan

Can you provide a self-contained example of what you did so far (i.e. code
for simulating some data and code for the plot)? That would greatly help to
help you find a solution.

Can you provide a self-contained example of what you did so far (i.e. code
for simulating some data and code for the plot)? That would greatly help to
help you find a solution.

Yes, but my issue is because I need to plot a pop pyramid with confidence
intervals, and the pyramid function does not work in that way. Thanks
Daniel.

Betreff: [R] Population pyramids

Hi, I hope somebody can help me with this issue: I am doing population
pyramids using the barplot command, so in the left side I have male age
structure and in the right side the female age structure. To plot the male
age structure I put the data in negative numbers. Now, I want to change the
sign in the bar plot in such way that I have no-sign numbers, both in left
and right side of the graph. I have been trying all day long and I could not
succed.

Thanks...

Victor

That was definitely helpful.

"if you change your seq to: seq(chunksize, 10000-chunksize, chunksize) 
then you won't get the error messages"

Even previously, I was not getting any error messages or warnings at 
all, i.e., "update" removes the extra NA rows silently, for example:

set.seed(1)
xx = data.frame(x1=runif(10000,0,10), x2=runif(10000,0,10), 
x3=runif(10000,0,10))
xx$y = 3 + xx$x1 + 2*xx$x2 + 3*xx$x3 + rnorm(10000)
fit1 = biglm(y~x1+x2+x3, data=xx[1:7000,])
fit2 = update(fit1, moredata=xx[7001:10000,])
fit3 = update(fit2, moredata=xx[7001:14000,])

Here fit2 and fit3 are exactly same.
Also if the number of rows is not a multiple of chunksize then your 
sequence will not accommodate the last small chunk of data .

If df is your dataframe then names(df) contains the column names and so names(df)[i] is the name of i-th column.

Dear All,

here is the example for cumulative incidence analysis with cmprsk package:


set.seed(2)
ss <- rexp(100)
gg <- factor(sample(1:3,100,replace=TRUE),1:3,c('a','b','c'))
cc <- sample(0:2,100,replace=TRUE)
strt <- sample(1:2,100,replace=TRUE)
print(xx <- cuminc(ss,cc,gg,strt))
plot(xx,lty=1,color=1:6)

When I
perform this example, I have 6 curves. 
a 1
b 1
c 1
a 2
b 2
c 2

I would
like to plot only 3 first curves of risk  cc=1 not all of 6 curves.
a 1
b 1
c 1
How I can
do this with R ?
Many thanks
Jan

The problem is that as.dendrogram isn't working on the pvclust objects.

One possibility is to use sink (see ?sink).

for that 
q[crossRsorted[,1]]

works but your real list is much more complicated.

and referring to what you wrote to Henrique

This appears to be doing something different. For instance, my 'q' has 165
components, but what you suggest has 15750:
> length(q)
[1] 165
> length(q[ crossRsorted[,1] ])
[1] 15750

hardly what I want.

but this is what you asked for.

crossRsorted has 15750 items and all has been selected from q.

length(q[ unique(crossRsorted[,1] ]))
could be what you are looking for. However the result is probably a list 
of data frames not a data frame with "rows".

Since I don't have root access to the CentOS machine, I can't make use
of that suggestion.  However, by modifying the ldpaths file in my home
directory where R is instaled, I could make it the same as it was in
the 2.8.1 installation.

Just why that wasn't a problem before R-2.9.0 and only with CentOS,
I'm no closer to understanding, but I know how to get around the
problem.

Thanks for the suggestion and the one from Godmar Back.  I have it
working.

Not so weird. What do you expect from

c(1:5, 10:20, 30:50)

That is basically what your function do. With slight modification you can
get tabular output without mapply

multipleoutput <- function (x) {
result.s <- x^2
result.c <- x^3
result.e <- exp(x)
cbind(square=result.s, cube=result.c, exp=result.e)
}

If the output could be mixed type }numeric, character, ...) use data.frame
instead of cbind

Dear all,

I'am using mlogit to test IIA hypothesis. I'get the test statistique who is negative, a p-value of 1, and a text saying that the IIA hypothesis is rejeted. Does a negative value mean that constraint model is more efficient that that the full model ? what to do in this case ?

Thanks a lot..! What exactly the sweep function is doing? Also, is there a
possibility instead of using the mean of the whole row to get only the mean
of a group of the row values? So the values in the matrix (heat map) used in
the comparison are z-scores and not the intensities of the gene expressions,
right?

Also, as I can understand from the code, heatmap is using distfun function
for the clusering. Can I use pearson correlation for the clustering? My main
object of using the heatmap is to examine the expression levels of the
marker genes and to confirm that the marker genes are clearly differentially
expressed in the two subtypes of the disease that I examine.

Many thanks,

Chrysanthi.

Hi R Fans,

I stumbled across a strange (I think) bug in R 2.9.1. I have read in a 
data file with 5934 rows and 9 columns with the commands:

daten = data.frame(read.table("C:/fussball.dat",header=TRUE))

Then I needed a subset of the data file:

newd = daten[daten[,1]!=daten[,2],]

--> two values do not meet the logical specification and are dropped.

The strange thing about it: When I print the newd in the R Console, the 
output still shows 5934 rows. When I check the number of rows with 
NROW(newd) , I get 5932 as output. When I print newd[5934, ], I get NAs. 
When I print newd[5932, ] I get the row that is listed in line 5934 when 
I just type in newd. This is totally crazy! Has anyone had the same 
problem? Thanks for a post.

Marc

Hello everyone,

Say I have zoo object

x.Date <- as.Date("2003-02-01") + c(1, 3, 7, 9, 14) - 1
x <- zoo(rnorm(5), x.Date)
y <- zoo(rt(5, df=2), x.Date)
z <- zoo(rt(5, df=5), x.Date)

Data <- merge(x,y,z)

What should I do to make the latest values appear at the top?

You're confusing row names and row numbers. When you printed newd, did 
you actually count the number of lines? Thought so...

It isn't any stranger than this:

No 5932 rows, but with the original rownames (with 2 of them missing).
