Hello !

There is something quite simple I want to do with R but I found nowhere in the help how to do it.
I just want to plot data which are in a matrix, every column being a data set and having the same
x-axis (just an index).

So for example if I have a 50 x 6 matrix I want 6 set of points on the same plot.

I tried

but it replaces the previous plot each time.

Thank you very much if you can help !
