To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

Onderwerp: [R] Newbie in R: Reading .txt files and storing the 'numbers'
in avector


Hello everybody,

I'm a newbie in R and just went through an introduction class recently.

Here's my problem.
I have 2 text files (.txt) with plain numbers ('doubles' for those who
know c++) ordered into 2 columns as below:

coordinate1		value1
coordinate2		value2
coordinate3		value3
...				...
coordinateN		valueN

I would like to write a small programme in which i would:
1. take all values of file 1 and store them in a vector 2. substract to
those all values of file 2 (one by one) and store the result in a new
vector 3. Create a sliding window of chosen size and calculate the
mathematical average and store these averages in a new vector 4. Plot
the different graphes with a bar plot

So I wrote a c++ script that does the first parts and writes the
averages in a output.txt file (which I have up and running).  
Unfortunately, I seem to fail in reading these as numbers and putting
them into a vector (in the R environment). I can read the file , but
this is what I get:

 > z=scan(file = "/Users/NCCRGENETICS/Desktop/testRnumbers.txt", what =
"double") Read 19 items  > z
  [1] "{\\rtf1\\ansi\\ansicpg1252\\cocoartf949\\cocoasubrtf430"
  [2] "{\\fonttbl\\f0\\fswiss\\fcharset0"
  [3] "Helvetica;}"
  [4] "{\\colortbl;\\red255\\green255\\blue255;}"
  [5] "\\paperw11900\\paperh16840\\margl1440\\margr1440\\vieww9000\
\viewh8400\\viewkind0"
  [6] "\\pard\\tx566\\tx1133\\tx1700\\tx2267\\tx2834\\tx3401\\tx3968\
\tx4535\\tx5102\\tx5669\\tx6236\\tx6803\\ql\\qnatural\\pardirnatural"
  [7] "\\f0\\fs24"
  [8] "\\cf0"
  [9] "13\\"             		// This is where my file
"should" start  
reading the numbers I see in the window when I open it with textedit
[10] "27\\"
[11] "39\\"
[12] "48\\"
[13] "34\\"
[14] "17\\"
[15] "23\\"
[16] "45\\"
[17] "23\\"
[18] "4\\"
[19] "}"

Thanks so much to any of you who could provoid a little help... I'm
getting nuts.
Patrick
