Dear Tim,

Have a look at the ggplot2 package.

ggplot(your.data.frame, aes(x = EducationYears, y = Income, colour =
Registered)) + geom_point()

You find a lot of examples at the ggplot2 website:

Does anybody know how to adding colors to data points in scatter plot in

I have the following R data frame -

Voter_Name, Education_years, Income, Registered Ricky, 18, 40000, Y
Lisa, 20, 34000, N Jon, 10, 35000, Y ...

I am doing a scatter plot in R for those data points - Income vs. 

I would also like to using different colors to differentiate whether
that data point is a Registered Voter or not.

Does anybody know how to adding colors to data points in scatter plot in

Thanks in advance!!
