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))
It's not necessary to embed the color names in the factor.
Hope this helps,

I have been trying to find a way to label my cluster with the

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)))
# This should work:
plot(y~x, col= c("blue", "green", "red")[f] )
