classmap: Visualizing Classification Results

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. <doi:10.1080/00401706.2021.1927849> (open access), Raymaekers J., Rousseeuw P.J.(2022).
