Please stop posting Mac-specific questions on R-help.  You have been 
asked not to do so before ....

There _is_ a quartz.save() function in R.app, whose FAQ you are reading.

The RMacOSX-FAQ is not part of R: it is part of the separate Mac-GUI 
project.   You really do need to contact the authors of that project via 
R-sig-mac, and use their version numbers, not R's.
