select_linkage: Cluster algorithm selection and validation
Description
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.
Usage
select_linkage(x)
Value
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.
Arguments
x
a numeric matrix, data frame or "dist" object.
