You may want to consider a dotchart instead of a barplot. Then you can
distinguish between groups by using symbols, grouping, and labels rather than
depending on colors/shades of grey.

Subject: [R] Problem with colormodel in pdf driver
I'm trying to create figures in PDF that use the 'gray' colormodel
instead of the default 'RGB' model, by requirements of a publisher.
My problem has to do with the fact that I'm not being able to get gray
colors with this option on the pdf() driver. Here is a small example
for
problem replication:
R.version
_
platform i486-pc-linux-gnu
arch i486
os linux-gnu
system i486, linux-gnu
status
major 2
minor 8.1
year 2008
month 12
day22
svn rev47281
language R
version.string R version 2.8.1 (2008-12-22)
pdf('exp.pdf',colormodel='gray')
barplot(table(subset(iris,Petal.Width1)$Species))
dev.off()
Contrary to what I was expecting the bars appear in black and not gray
as they are supposed to. This is not particularly serious for this toy
graph but for others it creates more problems.
Interesting enough this problem does not occur with the same option on
the postscript() driver as it can be observed by running:
postscript('exp.eps',colormodel='gray')
barplot(table(subset(iris,Petal.Width1)$Species))
dev.off()
Any help is most appreciated.

Re: [R] Problem with colormodel in pdf driver
Hi Luis,
Following David's suggestion, it worked for me:
pdf('exp.pdf',colormodel='grey') # Note the change here :)
barplot(table(subset(iris,Petal.Width1)$Species))
dev.off()
Here is my session info:

colormodel
a character string describing the color model: currently allowed values are
rgb, gray and cmyk. Defaults to rgb.
I got the expected behavior by making the gray - grey change on my Mac
OS 10.5.6/R2.8.1 system.

Re: [R] Problem with colormodel in pdf driver
'gray' is what is in the code: 'grey' uses rgb -- just look at the pdf
produced.
The issue is that the wrong ('stroke' not 'fill') colour is set in ht
'gray' colormodel.
