[R] Preparing high quality figures with tiff as end result

[Prof Brian Ripley]

Try bitmap(): this produces PostScript and converts with ghostscript.

BTW, everything (including text) in TIFF files *is* 'low-res bitmaps' by 
definition, so you cannot avoid this.  Anti-aliasing *may* help, and the 
bitmap() device in R-devel supports it.

Which means what?
