Have two sets of scatterplot data

?plot
?points

You will probably need to get some R basics down as to how to index certain
subsets of your data. This you find in any introductory R manual.

Hi,

You could take a look at the ggplot2 package.

good luck,

If the data are from one data.frame (e.g., the iris data set), then simply label
the red and white flowers with different colors:
e.g.,

with the iris data set

plot(iris$Sepal.Length,iris$Sepal.Width,col=c("red","blue","black")[iris$Species],pch=c(16:18)[iris$Species])
