[R] Simplifying Sweave graphics

[Stéphane Dray]

Hi.
One guy of my team (Thibaut Jombart) wrote a driver to sweave in png 
(see http://tolstoy.newcastle.edu.au/R/devel/06/03/4599.html). The 
driver works very nice and is very useful for plots with many points, 
raster images... I thought that Friedrich Leisch would include it in the 
Sweave distribution, but it is not in the current distribution.
I am sure that you can ask Thibaut (jombart_at_biomserv.univ-lyon1.fr) 
for the function.

Sincerely.
