pROC 1.2 released

The version 1.2 of pROC has just been released.

The main feature of this new version: the confidence interval of an AUC can be computed with the DeLong1 method.

library(pROC)
data(aSAH)
rocs100 <- roc(aSAH$outcome, aSAH$s100)
ci(rocs100)

Obviously they can still be computed with bootstrap:

ci(rocs100, method="bootstrap")

But the DeLong method is significantly faster. It works on full AUC only – for partial AUC you still have the bootstrap only.

Here is the full change log:

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.
