[R-SIG-Mac] tiff output

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.
