This function contrasts different hierarchical clustering algorithms on the phylogenetic beta diversity matrix for degree of data distortion using Sokal & Rohlf’s (1962) cophenetic correlation coefficient.
a numeric matrix, data frame or "dist" object.
A numeric value corresponding to the good clustering algorithm for the distance matrix
If plot = TRUE, a barplot of cophenetic correlation for all the clustering algorithms is drawn.
