upgma: UPGMA, WPGMA and sUPGMA

Description

UPGMA and WPGMA clustering. UPGMA and WPGMA are a wrapper function around hclust returning a phylo object. supgma perform serial sampled UPGMA similar to Drummond and Rodrigo (2000).

Usage

upgma(D, method = "average", ...)
wpgma(D, method = "mcquitty", ...)
supgma(D, tip.dates, trace = 0)

Value

A phylogenetic tree of class phylo.

Arguments

D

A distance matrix.

method

The agglomeration method to be used. This should be (an unambiguous abbreviation of) one of "ward", "single", "complete", "average", "mcquitty", "median" or "centroid". The default is "average".

...

Further arguments passed to or from other methods.

tip.dates

A named vector of sampling times associated to the tips.

trace

Show output during optimization (see details).
