I sent a new minor version of pROC (1.5.1) to the CRAN.

This version fixes a bug that would make slow down the loading of pROC on computers with many packages. Thanks to Prof Brian Ripley and Glenn Lawyer for the report.

The new version is available on ExPASy and on the CRAN. To update, type update.packages() or install.packages("pROC") if you want to update pROC only.
