If you know explicitly that there are just 60 points, you can use:
plot(csr(),col=c(rep('blue',20), rep('red',20), rep('green',20)))

Hi,
I have the following code to
randomly generate the
points:
csr <-function(n=60){
x=runif(n)
y=runif(n)
f=cbind(x,y)
}
plot(csr())
I wonder how to code to make the first twenty points to be BLUE; second twenty
points to be RED; the last twenty points to be GREEN?
Thanks,
Sam
