Plot a time-varying AUC curve

Source: R/plot.gg_auct.R
plot.gg_auct.Rd

Draws AUC(t) from a gg_auct() object: a line over time, a bootstrap confidence ribbon when available, and a dashed reference line at 0.5 (chance). The integrated AUC (iAUC) appears in the caption. Times with a non-finite AUC are dropped before drawing: from randomForestRHF 2.0.0 the final grid time can be NA, where the censoring-weight denominator is undefined once the control set is nearly exhausted.
