[R] R from outside program

[Sean Davis]

You'll probably need to send your cmdfile.R to see what is in it, as 
that is where the problem likely is.  However, if you do something 
line:

pdf('my.pdf')
plot(1:10,1:10)
dev.off()

in your cmdfile.R, you will get a pdf file of the plot saved in the 
directory where you ran your script.  Note that you need to open a 
device like pdf, png, etc. for plots to be saved.  They aren't saved 
automatically
