?points has this example plot(-4:4, -4:4, type = "n")# setting up coord. system points(rnorm(200), rnorm(200), col = "red") points(rnorm(100)/2, rnorm(100)/2, col = "blue", cex = 1.5)
In general you might want to check out the keyword section of the help, in particular the Graphics section which has an entry called aplot for ways to add to existing plots.
