GetClade: Get clade from the tree

Description

Search and report the nodes of the tree that have the desired clade size.

Usage

GetClade(phy, clade.size)

Arguments

phy

an object of class 'phylo'.

clade.size

size of the clade.

Value

the interior node that has descedants of size clade.size on the tip.

Details

This function uses the 'phylo' class where the edges(ancestor-decedant relationship) of the tree are used to identify the interior node with desired number of descedent (clade.size) on the tips. It applies the function findMRCA in phytools to search the ancestor.
