[R] [R-pkgs] pROC 1.4.3: compare two ROC curves in R

[Xavier Robin]

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
* Comparison of two ROC curves (curves and AUC)
* Calculating and plotting confidence intervals
* Smoothing of the ROC curve
* Coordinates extraction ('coords' function).

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
* DeLong [1] method for full AUC
* Venkatraman [2, 3].

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)
* ROC coordinates (thresholds, sensitivity or specificity).

You can find more information in our paper [4] and on pROC website:

Hope you'll find it useful!
