[R] Scatterplot question

[judith.baltsar@gmx.de]

Dear list members,
I have a probably simple question concerning scatterplots: I want to 
draw a plot with one X but several Y columns, so that every group 
of samples gets a different symbol. My table looks like this:

X	Y1	Y2	Y3
1	1
2	3
3	5
4		7
5		9
6		11
7			13
8			15

Simple in Excel or StarOffice, but how do I do it in R?

Thanks a lot

Judith
