[R] graphic device MetaPost

[Itay Furman]

The TeX world offers several comapnion systems to typeset 
graphics; metapost, xy-pic, and PSTricks are the most powerful, 
and have facilities for typesetting data plots. Recently, the pgf 
LaTeX package, that can coop with PDF and PS from the same 
source, was submitted to CTAN; but it is more restricted than the 
others.

>From time-to-time I played with the idea of writing such 
mentioned device. The trouble is, that I feel it is beyond my R 
and TeX skills (for the moment, at least).
If no one picks up this glove -- then I will attempt this 
venture.
If you would like to see such a device(s), and would like to 
contribute, maybe we can team up.

To the original poster: could you use the pictex() device
for your needs?

	Thanks,
	Itay Furman
