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

[Don MacQueen]

I know this is not helpful for folks who don't have Illustrator, but 
as of today I got decent results using R's postscript() device to 
create an EPS file, opening it in Illustrator (v10), and exporting as 
WMF.

The image, then imported into either Word 2004 or PowerPoint 2004 was 
decent, in the single example I tried. Certainly much better than 
using R's pdf() and then importing directly into Word or PP.

Watch out for encoding issues; believe it or not, specifying 
encoding='WinAnsi' in postscript() may give the best results.
