pROC 1.7 was released. It provides additional speed improvements with the DeLong calculations now implemented with Rcpp, improved behaviour with math operations, and various bug fixes. It is now possible to pass multiple predictors in a formula: a list of ROC curves is returned. In details:

• Faster algorithm for DeLong roc.test, power.roc.test, ci.auc, var and cov function (no large matrix allocation)
• Handling Math and Operations correctly on auc and ci objects (see ?groupGeneric.pROC)
• The formula for roc.formula can now provide several predictors and a list of ROC curves will be returned
• Fixed documentation of ci.coords with examples
• Fixed binormal AUC computed with triangulation despite the claim in the documentation
• Fixed unstated requirement on Rcpp >= 0.10.5

pROC 1.7.1 is an quick fix release to get the package on CRAN.

• Close SOCK cluster on Windows with parallel=TRUE
• Fixed really use algorithm 1 when microbenchmark fails
