The basic unit of the pROC package is the roc function. It will build a ROC curve, smooth it if requested (if smooth=TRUE ), compute the AUC (if auc=TRUE ), the confidence interval (CI) if requested (if ci=TRUE) and plot the curve if requested (if plot=TRUE ). The roc function will call smooth , auc , ci and plot as necessary.
