+and ROC curve for weighted (e.g. soft-labeled) and unweighted data. In
+contrast to other implementations, the interpolation between points of the PR
+curve is done by a non-linear piecewise function. In addition to the areas
+under the curves, the curves themselves can also be computed and plotted by a
+specific S3-method.")
