[R] exporting high quality graphics from R in Mac OSX

I almost always do a bit of tweaking of my R graphics (output as postscript
files) using Adobe Illustrator. The latest version has the option of saving
the file "For Microsoft Office..." under the File menu. The resulting *.png
file comes up clean in PowerPoint or in Word.

Cheers, George
