Hello,

You search that command :

plot(x1,x2,pch=rep(1:4,50))

Oups, sorry, I meant that :

plot(x1,x2,pch=rep(1:4,each=50))
                      ^^^^


I need more cafeine on morning !



I think you should read some basic manuals about R, the FAQ, etc ...

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
