aucRoc and roc functions in the caret R package

Question

I am reading the caret R package's paper on the Journal of Statistical Software link , and on pages 15-16, the author introduced the use of calculating ROC and AUC. However, since version 5.13-037 these functions are no longer available (see here ). I think they're convenient functions but not sure why they're deprecated.... Any suggestions on alternative approaches/functions for ROC and AUC? Thanks!

Answer 1

You can use pROC package for example:

library(pROC)
data(aSAH)
# Basic example with 2 roc objects
roc1 <- roc(aSAH$outcome, aSAH$s100b)
