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

Thu Feb 10 19:11:08 CET 2005

Well it would be more logical for Microsoft to support pdf! I've  
certainly complained loud enough, but I don't count on them doing  
something for me. Unless pdf becomes important on Windows, I suppose.

As for a R-based solution, a pict device would solve my problem just as  
well as a wmf device.
