Description

Ratio of the mean phylogenetic distance between the tips in subtree to the mean phylogenetic distance between the tips in whole tree.

Usage

RMPD(subtree, tree)

Arguments

subtree

A subset of phylogenetic tree

tree

A phylogenetic tree

Details

RMPD > 1 indicate the tips in the "subtree" are less phylogenetic related than in "tree". This ratio could be used as a representative of phylogenetic relationships of species that occurred in subtree in comparison with in "tree". RMPD < 1 indicate the tips in "subtree" are more close related
