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

I would love to get Keynote, but it is not compatible with my old 
powerbook. As my employer had put a freeze on computer purchases 
because of budget constraints (and because buying a Mac where I work is 
a big struggle, as I'm seen as a thorn in the (chose your soft spot) of 
the IS guys who'd love to have a 100% Windows universe, but that's 
another story) it is not an option (yet).

Actually in recent versions of PowerPoint wmf usually display properly 
and very sharp. In a presentation I gave yesterday the only sharp 
graphs came from wmf maps I produced with Surfer on a Windows machine, 
what a shame!

But I can certify that PowerPoint always allowed vector pict format.

For now I'll have to resort on running some R programs a second time 
and save higher resolutions png than what Preview and Illustrator give 
me when they translate pdf into png.
