pROC 1.2.1 has been released.

The first change is to handle method arguments for smooth.roc and ci.auc separately in roc.default, fixing the conflict. Now you can write:

library(pROC)
data(aSAH)
rocs100 <- roc(aSAH$outcome, aSAH$s100, smooth=TRUE, smooth.method="density", ci=TRUE, ci.method="delong")

The second change is added auc.polygon.* and max.auc.polygon.* arguments for polygon in plot.roc. For instance:

rocs100 <- roc(aSAH$outcome, aSAH$s100, partial.auc=c(1, 0.9))
plot(rocs100, auc.polygon=TRUE, auc.polygon.col="green", auc.polygon.lty=2, auc.polygon.density=25, auc.polygon.angle=45, auc.polygon.border="blue")

Here is the full change log:

• Handle method arguments for smooth.roc and ci.auc separately in roc.default (R-only).
• Added auc.polygon.* and max.auc.polygon.* arguments for polygon in plot.roc.

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.
