[R] Merge postscript files into ps/pdf

The best approach if creating all the files using R is to change how you create the graphs so that they all go to one file to begin with (as mentioned by Joshua), but if some of the files are created differently (rgl, external programs), then this is not an option.  

One external program that is fairly easy to use is pdftk which will concatenate multiple pdf files into 1 (among other things).  If you want more control of layout then you can use LaTeX which will read and include ps/pdf.

If you need to use R, then you can read ps files using the grImport package and then replot them to a postscript/pdf device with onefile set to TRUE.
