Dear R Masters,

I have searched high and low (the help archives and my various R reference material and help files) for a solution to what appears to me to be quite a simple problem.  In the following syntax, variable n10 has three levels.  I would like the symbols that appear in the graph for these three levels to be different colors.  The best I have been able to do is to have the Key display three colors, but the symbols in the graph only show up in black and white.  Any suggestions?

par(cex=.8)
s <- summary(n10 ~ n13, method="reverse", test=T)
plot(s, dotsize=1.2, cex.labels=.7, cex.axis=.5, cex.main=.5, which="categorical")
Key(locator(1))

R version 2.0.1
Windows XP

Thank you,
