Creating ordered colors for ordered factors

Hello,

Try the following.

g <- factor(c(rep("blue",10),rep("green",10),rep("red",10)),
   levels = c("blue", "green", "red"))
plot(y~x, col=levels(g)[g])
plot(y~x, col=as.character(g))

Hope this helps,

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=  c("blue", "green", "red")[f] )
