mdendro - Extended Agglomerative Hierarchical Clustering
A comprehensive collection of linkage methods for
agglomerative hierarchical clustering on a matrix of proximity
data (distances or similarities), returning a multifurcated
dendrogram or multidendrogram. Multidendrograms can group more
than two clusters when ties in proximity data occur, and
therefore they do not depend on the order of the input data.
Descriptive measures to analyze the resulting dendrogram are
additionally provided. <doi:10.18637/jss.v114.i02>.
