Marc and Partha,
Thank you both for your suggestions of using par("mfrow"), that's exactly
what I needed to do. In fact I already had it in the code (which I didn't
write originally) and simply had to put my postscript statement in front of
It works great now! Thanks for the quick responses.

Either one of the following work for me:
# Do 3 plots in a 2 x 2 matrix
postscript(file = "ThreePlots.ps", horizontal = FALSE) par(mfrow = c(2, 2))
# Do 3 x 1
postscript(file = "ThreePlots.ps", horizontal = FALSE) par(mfrow = c(3, 1))
Can you provide an example of the code that you are using?
