Have two sets of scatterplot data hypothetically a) stem lenght vs number of petals in red flowers b) stem lenght vs number of petals in white flowers want to place on same scatter plot with same x,y axis but different collored markers How do I do this in R -- View this message in context:

Re: [R] how do i put two scatterplots on same graph

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]) Bill On Oct 4, 2011, at
