%description
Tools to visualize the results of a classification or a regression. The
graphical displays include stacked plots, silhouette plots, quasi residual
plots, class maps, predictions plots, and predictions correlation plots.
Implements the techniques described and illustrated in Raymaekers J.,
Rousseeuw P.J., Hubert M. (2022). Class maps for visualizing
classification results. emph{Technometrics}, 64(2), 151–165.
