Correlated ROC curves

Hi,

Is there any package or code to compare and display correlated ROC curves in
R?

Thanks,
Reza

There are ways to compare ROC areas.  This will not have very good 
power.  The Hmisc package's rcorrp.cens function provides a test that 
deals with pairs of pairs of predictions and observed outcomes that I 
feel has much more power.  It tests whether one predictor is 'more 
concordant' with the outcome than another.
