I am a new user of R. Please does somebody knows how to plot 3 datasets (x1,a1),...,(xn,an), (x1,b1),...,(xn,bn), and (x1,c1),...,(xn,cn) on a single x,y plot, each of the three datasets being plotted with its own character pch() ? (three calls to plot() erase the two first datasets). Thank you very much.
