Samuel,
Since the difference in AUCs has insufficient power and doesn't really
take into account the pairing of predictions, I recommend the Hmisc
package's rcorrp.cens function. Its method has good power and asks
the question "is one predictor more concordant than the other in the
same pairs of observations?".

Hello,
Is there is any R function computes the AUC for paired data?
Many thanks,
