[R] plot

[Jacques VESLOT]

if * in x1[1:50,]*x2[1:50,] means "times", try :
matplot(matrix(x1,ncol=4)*matrix(x2,ncol=4))

if * means "vs", try :
matplot(matrix(x1,ncol=4),matrix(x2,ncol=4))

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
