(description
"This package computes the areas under the @dfn{precision-recall} (PR)
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.")
