In monoClust: Perform Monothetic Clustering with Extensions to Circular Data

Description

Calinski-Harabasz's pseudo-F (Calinski and Harabasz, 1974) and Average silhoutte width (Rousseeuw, 1987) calculation.

Usage

cluster_stats(d, clustering)

Arguments

d	Distance object (as generated by dist()) or a distance matrix between cases.
clustering	Integer vector of length of the number of cases, which indicates a clustering. The clusters have to be numbered from 1 to the number of clusters.

Value
