precrec calculates and plots ROC and precision-recall curves for binary classifiers. It is built for the case where the two curves disagree: on an imbalanced dataset a ROC curve can look excellent while the precision-recall curve shows the classifier is not usable. All the main calculations are implemented in C++ through Rcpp.
