Dear Amanda,
Try this:
# Data set
set.seed(123)
DF=data.frame(A=rnorm(10),B=rpois(10,10),C=sample(1:3,10,replace=T))
attach(DF)
# Plot
plot(A,B,pch=16,col=C)
legend('topleft',paste('Group',1:3,sep=" "),col=1:3,pch=16)
HTH,
Jorge

See argument 'col' to plot()/points(). Setup a 'col' vector of length
equal to the number of data points and have the 'C' variable specify
the colors of the individual elements. Then call plot()/points() with
argument 'col'.
