[R] R versions and PostScript files

[David Smith]

Another option in this specific case is to use the new useRaster=TRUE
option, which makes the image function generate much more compact and
faster-rendering image plots. This code:

setEPS()
postscript (file="volc.eps",width=5,height=4)
image(volcano,useRaster=TRUE)
dev.off()

in R 2.13 generates a 37Kb file which renders very quickly (compared
to a 193Kb file without using the useRaster=TRUE option).
