Hi,
This should do it. I let plot() choose whatever colors it wanted, but
if you really wanted you could set them manually. Many thanks to
David for the data.
plot(temp$V1, temp$V2, pch = as.character(temp$Class), col = temp$Class)
# As an alternative using ggplot2
# I do not use "A", "B", "C", but there are different shapes and there
is a nice legend
library(ggplot2)
qplot(x = V1, y = V2, colour = Class, shape = Class, data = temp, geom
= "point")
HTH,
Josh
