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])
