allFurcTrees: Generate all bi- and multifurcating unrooted trees

In phytools: Phylogenetic Tools for Comparative Biology (and Other Things)

Generate all bi- and multifurcating unrooted trees

Description

This function creates all possible unrooted bi- and multifurcating trees and returns a list of trees as an object of class "multiPhylo".

Usage

allFurcTrees(n, tip.label=NULL, to.plot=TRUE)

Arguments

n	an integer giving the desired number of species.
tip.label	an optional vector of length n containing the tip names.
to.plot	an optional logical value indicating whether or not to plot the trees.

Details

This function should be used with extreme caution for n greater than about 8, as in this case the number of possible trees is extremely large.

Value

A list of trees as an object of class "multiPhylo".
