[R] good procedure for creating plots for PowerPoint

[Russell Senior]

I am generating some graphs (on GNU/Linux using R 1.5.x) for a
PowerPoint presentation my boss is giving next week.  He just tried
cut/pasted a plot off of a PDF file I had created, but he complained
that the fonts were too small and fuzzy, and that he couldn't change
the background.  I have been playing with png(bg=transparent), but I
am not sure what appropriate height,width parameters and whether I
should modify my plot colors.  Any pointers on generating good quality
figures for PowerPoint?

Thanks!
