I just released a minor revision of pROC, version 1.5.3.

This version fixes the following bugs:

• AUC specification was lost when roc.test, cov or var was passed an auc' object.
• Incorrect computation of "accuracy" in coords.

As usual, you can find the new version on ExPASy and on the CRAN (please allow up to a few days before it is available for Windows). To update, type update.packages() or install.packages("pROC") if you want to update pROC only.
