Hi, Susan.

I believe that perhaps a colleague of yours asked this question
already today on the list.  But, to answer you, also, have a look at
the ROC package.  If you have further questions, please clarify your
question after read the posting guide here:

http://www.bioconductor.org/docs/postingGuide.html

and be sure to include the relevant information in future posts.
