Hierarchical clustering

Hierarchical clustering and dendrogram (WPGMA and UPGMA methods)

This function defines the hierarchical clustering of any matrix and displays the corresponding dendrogram.
The hierarchical clustering is performed in accordance with the following options:
- Method: WPGMA or UPGMA
- Metric: any anonymous function defined by user to measure vectors dissimilarity
- Clustering parameter: number of clusters or dissimilarity limit
The function returns the linkage tree, the clusters, the list of ranked items and optionally the dendrogram calculated on the basis of dissimilarity matrices.
