[R][Rdev] any way to generate "bitmap" (tif, jpeg, png etc) files in R CMD BATCH

Oleg, 

Please do not cross-post between r-devel and r-help. It is considered bad
taste.

This is a FAQ, see

http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-do-I-produce-PNG-graphics-in-batch-mode_003f

and, say, "?bitmap" in R.

Hth, Dirk
