Hello
That would do the trick :
x <- rnorm(50)
y <- rnorm(50)
color <- rep("blue",50)
color[(x>0)&(y<0)] <-"red"
color[(x<0)&(y>0)] <-"green"
color[(x<0)&(y<0)] <-"yellow"
plot(x,y,col=color,pch=19)
abline(h=0) #just to check
abline(v=0) #just to check

Thanks again Andy and Uwe for you help on my previous
post of ploting lm coef and means. With your
direction, I was able to expand and generalize the
function to meet my requirements.
Follow up question: Is it possible to make the points different colors depending on which quaderant they fall into?
The data frame contains two variables (x and y) Quad 1 = x>mean(x) & y>mean(y) would be blue Quad 2 = x>mean(x) & y<mean(y) would be red Quad 3 = x<mean(x) & y>mean(y) .... Quad 4 = x<mean(x) & y<mean(y) ....
