[R] R Graphs in Powerpoint

[Jarrett Byrnes]

Hey, all.  Quick question.  I'm attempting to use some of the great 
graphs generated in R for an upcoming talk that I'm writing in 
Powerpoint.  Copying and pasting (I'm using OSX) yields graphs that 
look great in Powerpoint - until I resize them.  Then fonts, points, 
and lines all become quite pixelated and blurry.  Even if I size the 
window properly first, and then copy and paste in the graph, when I 
then view the slideshow, the graphs come out pixelated and blurry.

Is there any good solution to this, or is this some fundamental 
incompatibility that I can't get around?
