R help - May 2004 - receiver operating characteristic (ROC)

Dear R users,

I would like to get some simple syntaxes for ROC curves for the
research  of thresholds and cluster analysis for preliminary regrouping
of variables for a simple scoring system.

Thanks.

www.bioconductor.org has an ROC package.  It stores the specificity and
sensitivity as an ROC object and can calculate partial areas.
