[R] density and jpeg

[Prof Brian Ripley]

Yes, *but* (because you keep on reporting misleadingly), jpeg() on Windows 
is a completely different device to jpeg() on Mac OS X.

jpeg() on Mac OS X with R 2.7.0 is based on Quartz, so this is a Mac 
OS-specific issue, for r-sig-mac and not here.

Folks, please do remember that there are lots of different graphics 
devices in R, and this is one area that is most tailored to different 
OSes.   There are no less then 4 separate jpeg() devices with a common 
interface.  That is why we keep asking for enough details about the 
environment you are using.
