[R-SIG-Mac] tiff output

[Carl Witthoft]

Personally I'd actually recommend saving the graphic in whatever is the 
highest-quality format you can, then open it in GraphicConverter and use 
that app to save a copy in tiff format.

It is a shame that there's still no tiff file tool in R (rtiff is old, 
bonged up, and ugly :-( ).  Matlab and GraphicConverter (and I believe 
GIMP) have no problem opening & converting tiffs.  We just need some 
energetic R-fan to code up a tool.
