R help - Oct 2010 - Help saving multiple graphics

I'm a new-ish user using a for loop to create many hundreds of plots. 
I'm
using the "par" function to create them in a 2x2 graphics window.  

What I'd like to do is output this 4-up graphic to a file every four plots. 
I really don't care what the filename is, but it would be useful to be able
to specify something like "plotnum_1."

Any tips on how to go about this?

You can get all the plots into one file of any name using the pdf command

pdf(filename,onefile=TRUE)

place this before your loop and say this after your loop

dev.off()

to stop writing pictures to that pdf file.

In this way you can capture lots of images, but be careful.  They will be
really high quality, and therefore you might get a really large file size.

for more say this in R
