I have been trying to find a way to label my cluster with the colors I want
using factors.  I am not having a good time.  I can make the plot I'm
looking for but how can I make it so I specify that my ordered factors have
ordered colors (1= "blue", 2="green", 3="red")?

x <- c(rnorm(10,1,1),rnorm(10,10,1),rnorm(10,10,1))
y <- c(rnorm(10,10,1),rnorm(10,10,1),rnorm(10,1,1))
f<- factor(c(rep(1,10),rep(2,10),rep(3,10)))
plot(y~x, col=f)

Thanks

Hans
