Hi Carlos,
This may be what you want:
zeep<-rnorm(20)
zeepcut<-as.numeric(cut(zeep,c(-4,-0.35,0.35,4)))
plot(zeepcut,col=c("red","yellow","green")[zeepcut])

At the risk of promoting my own code :-), if you want to plot lines
with this sort of value-dependent color instead of points (or in
addition), the function clplot() in the Plotrix package will do it for you.
