If z has column names (but do not use this

Gabor,
That combination is just what I was looking for. Now I can start using my
new knowledge on these

I think that my reading answered this question, but now I nee

To have several performance curves on a single plot, use the
"add=TRUE" option, e.g. as follows:
plot(perf1)
plot(perf2, add=TRUE, col='red')
Please read the help to ?plot.performance. It also tells you how you
can adjust all graphical parameters for the individual curves.

Thanks!
I am now also trying to plot several ROCs in the same figure using ROCR
package. The following code:
"pred1 <- prediction(yest1,ytest)
perf1 <- performance( pred1, "tpr", "fpr" )
plot( perf1 )
pred2 <- prediction(yest2,ytest)
perf2 <- performance( pred2, "tpr", "fpr" )
lines( perf2 )"

thanks you both for the reply.
yes, the second question is two-in-one, a bit confusing: I was thinking
about Matlab's hold
command, but also waiting for user input to proceed. So you have provided
the complete answer.
The first question though - yes, windows() will give you a different window

Hi Oliver,
1) thats easy, if you want to display several graphs at once type windows(),
once for each new graph.
2) Not sure exactly what you mean here but you have complete control over

using points(), etc. etc.
