Cluster
(Hierarchical Clustering Package Symbol) Cluster[c_1, c_2, d, n_1, n_2] represents a merger of the clusters c_1 and c_2 with dissimilarity d and n_1 and n_2 data elements respectively.
ClusterSplit[c, n] splits the cluster c into n clusters.
DendrogramPlot[list] constructs a dendrogram from the hierarchical clustering of list.DendrogramPlot[c] constructs a dendrogram from the Cluster object c.
DirectAgglomerate[m] constructs a cluster hierarchy based on the distance or dissimilarity matrix m.DirectAgglomerate[m, list] associates the elements of list with the rows ...
DistanceMatrix[list] gives a matrix of distances or dissimilarities between the elements of list.
