I just released pROC version 1.4.4.

This version fixes a critical bug in the computation of one-tailed ROC tests p values. Please update to this version if you perform one-tailed tests.

library(pROC)
data(aSAH)
rocs100 <- roc(aSAH$outcome, aSAH$s100)
rocwfns <- roc(aSAH$outcome, aSAH$wfns)
roc.test(rocs100, rocwfns, alternative="greater")
roc.test(rocs100, rocwfns, alternative="less")

Thanks to Lisa Koch for pointing out the problem.

Here is the full change log:

• Fixed alternative for one-tailed tests.
• Removed COPYING file to fix a warning in r-devel.

As usual, you can find the new version on ExPASy and on the CRAN. To update, type update.packages() or install.packages("pROC") if you want to update pROC only.
