[R] Working with R batch

[Shai Shen-Orr]

Hi all,

I'm trying to invoke R from a perl program, using R BATCH.  My original
R program wrote an output to a file and plotted a graph.  I'm having
problems with the following three things:

1) To get the output file name form the perl program I wrote the
following, in my R program:
 commandArguments <- commandArgs();
outputFile <- commandArguments[length(commandArguments)];

This seems to not have worked.  Any ideas on why, or how else should I 
be doing it ?

2) For some reason when I'm using R BATCH, my plot doesn't come up, I
remember reading someplace that sometimes there might be problems with
graphics & batch, but does anybody know how to get passed them ?

3) How can I print a plot ?  Is it only through the postscript() command
?


	Thanks,


	Shai
