This tutorial walks you through, step-by-step, how to draw ROC curves and calculate AUC in R. We start with basic ROC graph, learn how to extract thresholds for decision making, calculate AUC and partial AUC and how to layer multiple ROC curves on the same graph.

You can get a copy of the code from the StatQuest GitHub, here:
