[R-SIG-Mac] How to put nice R graphics into powerpoint

Thank you Andrew and Thomas,

I have used png produced by Illustrator in much the way you described  
and the results were not very good. I'll try again because I don't  
remember if I was given an option to chose the overall size in pixels.  
If I can, then I'll increase the count. Alternatively, on my iMac at  
home where R11 is installed, I'll resort to saving directly in png but  
increasing the pixel count, as suggested by Thomas.

Still, if the information in the pdf produced by R is vector based (it  
is still perfectly sharp when viewed at 1600% in Acrobat), why can't I  
find a way to transform such pdf in vector-based pict? That format must  
be able to handle such plots. After all, I also make plots in  
KaleidaGraph, and they were very small vector-based pict files. They  
looked gorgeous in Powerpoint at any zoom setting. I also use Aabel  
which gives you the option of saving plots as pdf or pict. I chose the  
later when I need to insert in PowerPoint, and the former for LaTeX.  
Quality is good either way. Maybe I'll check if there is a "graphics"  
discussion on Apple's site. If I manage to learn something useful I'll  
report back.
