The function computes the area under the receiver operating characteristic curve (AUC under ROC curve).
AUC < 0.5, a warning is printed and
1-AUC is returned. This
behaviour can be suppressed by using
switchAUC = FALSE
The implementation uses the connection of AUC to the Wilcoxon rank sum test; see Hanley and McNeil (1982).
