You may want to consider a dotchart instead of a barplot. Then you can

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...
Thanks all for the help.
