[R] Batch

[partha_bagchi@hgsi.com]

You haven't given much detail to go on. So I have to make some assumptions 
(feel free to correct me if I am wrong):

1. You already know how to plot something in R from the R command line.
2. You know how to save your plotting commands in a text file (say 
fancyplots.R).

If these are true, then say you define 
$r_file = "/path/to/fancyplots.R";

Let
$Rbin = "/usr/local/R/bin/R"; #I am assuming you are on *nix

Then this should work (untested - so use at your own risk!!)[modify to 
your needs]:

  open(R, "| $Rbin --no-save > temp.out");
  print R "source(\"$r_file\")\n";
  close R;

Obviously there may be other sophisticated ways to do this.

HTH,
Partha

Dear ladies and gentlemen,
I want to automatise my data-analysis with R. What I exactally want to do, 
is to start  R - functions out of a perl-skript and do some batch 
plotting.
But I have no idea how to realise  this. Can anybody help me?
Thank you very much.
With kind regards

Claudia Paladini
