Dendrogram

Plot distance matrix, two dendrograms and color bar: save the figure (.png)

Description

It is necessary to calculate the pairwise distances between all elements.

There are routines for agglomerative clustering:
(1) average linkage: it will be the mean of the distances of the joining clusters weighted by the number of elements each cluster holds. Disadvantages: Average-link clustering may cause elongated clusters to split and for portions of neighboring elongated clusters to merge.
(2) centroid linkage: each cluster is defined by its centroid: a data point that represents all the points included in the cluster.

Parameters

connectivity_matrix: Connectivity Matrix ( input )

transpose: Boolean ( input )

linkage_method_X: Choice ( input )

linkage_method_Y: Choice ( input )
