Dear R users,

pROC is a package to compare, visualize, and smooth receiver operating characteristic (ROC) curves.

The package provides the following features:
* Partial or full area under the curve (AUC) computation

The main feature of pROC is the comparison between two ROC curves. Three methods are currently implemented for both paired and unpaired ROC curves:
* Bootstrap for full and partial AUC and smoothed ROC curves

Confidence intervals can be computed with bootstrap for both empirical or smoothed ROC curves:
* partial or full AUC (also with DeLong [1] method for full AUC)

You can find more information in our paper [4] and on pROC website: http://www.expasy.org/tools/pROC/

Hope you'll find it useful!
