[R-SIG-Mac] Quartz.save in R 2.6

[Daschbach, John L]

In earlier versions of R I used quartz save to save graphics from a script.
This no longer works.  What is the current mechanism to save quartz graphics
programmatically.  This should be doable from Applescript, but that's a bit
of work.

Thanks.
