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

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 )"

Hi,
I am new to R. I have two questions about plotting in R:
1. How to plot several lines in a figure? Suppose I have several sets of
points (xi,yi), where xi and yi are equal-length vector. plot(x1,y1) will
give a line connecting these points. Another plot(x2,y2) will erase what
plot before and

hi,
There are two types of plotting I miss dearly in Matlab, can anyone
enlighten me how to do similar stuff in R?
- multiple figures with individual windows (not multiple figures in
same window)?
- draw something, hold on the drawing, wait for a key action, then
overlay on top?
