[R] nice report generator?

[Tal Galili]

Hello again Duncan,
I am sorry it took me two days to get back to your response.

Regarding reshape -
It is well presented here: http://www.jstatsoft.org/v21/i12
And there is also more information about it here: http://had.co.nz/reshape/

After playing around with it, I wrote a small "bridge" between {reshape}
and {tables} in a function called "tabular.cast_df".  I am attaching the
code (with self contained examples) to this e-mail.

I would be happy for any revisions from either you or anyone else on the
list.

While working on this, I found something which might be a bug in {tables}
(either in the way I am using the function, or in the way that it works),
please see example bellow:




# loading libraries
library(tables)
library(reshape)

# getting our data ready
names(airquality) <- tolower(names(airquality))
airquality2 <- airquality
airquality2$temp2 <- ifelse(airquality2$temp > median(airquality2$temp),
"hot", "cold")
aqm <- melt(airquality2, id=c("month", "day","temp2"), na.rm=TRUE)
colnames(aqm)[4] <- "variable2" # because otherwise the function is having
problem when relying on the melt function of the cast object
head(aqm,4)
  # month day temp2 variable2 value
# 1     5   1  cold     ozone    41
# 2     5   2  cold     ozone    36
# 3     5   3  cold     ozone    12

# possible BUG ?!
tabular(month*temp2~variable2*result_variable, data = m_xx)
# this one gets the "temp2" header in the first 2 columns (instead of in
only the second column).
