Keywords
cluster
##### Usage
coalSpeciesTree(tree, X = NULL, sTree = NULL)
##### Arguments
tree

an object of class multiPhylo

X

A phyDat object to define which individual belongs to which species.

sTree

A species tree which fixes the topology.

##### Details

coalSpeciesTree estimates a single linkage tree as suggested by Liu et al. (2010) from the element wise minima of the cophenetic matrices of the gene trees. It extends speciesTree in ape as it allows that have several individuals per gene tree.

##### Value

The function returns an object of class phylo.
