[R] plotting grouped data object

[Afshartous, David]

Hello Xiaohui,

data.grp is just a pseudo example of a grouped data object
that is grouped according the factor y.
I just tried your suggestion, but the result is that 
three separate panels are still created, whereas I would like
to have all 3 lines in a single panel.  

cheers,
dave

I don't get your meaning in what is in datagrp, anyway, try:

X11()
par(new=T)

before calling:
plot(data.grp, outer = ~ y)
