Thanks Greg. The only problem is that I was trying to illustrate the use of
barplot() ...
I guess for now I can always use the pdf() driver with the default RGB
colormodel and then use command line tools (e.g. ImageMagick) to convert the
resulting graphs to grayscale...
You won't be able to convert PDF to PDF with ImageMagick (possible
with a helper).
Thanks all for the help.
Or update your R, as the posting guide suggested. It works in
R-patched and R-devel.
