[R] Multiple colors in plots/lookup function

Hello,
  I'd like to do something like:

 n<-100
 zz<-cbind(rnorm(n),rnorm(n),floor(runif(n)*3+1))
 colors<-c("red","green","blue")

 plot(zz,col=colors(zz[3]))

and have a matrix of scatterplots colored by class.  The above does not
work, of course, but I'm not sure exactly what function I'm looking for.

Thank you for your time,
Dave,
