hello,
I wonder whether there is a way to plot in R the following:
I have two arrays of dimension (200*1) say x1 and x2.
I would like to plot on the same graph x1[1:50,]*x2[1:50,] with pch=1
x1[51:100,]*x2[51:100,] with pch=2
x1[101:150,]*x2[101:150,] with pch=3
x1[151:200,]*x2[151:200,] with pch=4
is it possible with the "plot" function? Or do I have to plot
4differents graphs?
THanks in advance.
nicolas
