genETMTree {poweRbal}

Generation of rooted binary trees under the equiprobable-types-model (ETM)

Description

genETMTree - Generates a rooted binary tree in phylo format with the given number of n leaves under the equiprobable-types-model. Given n, all tree shapes/topologies with n leaves are equiprobable under the ETM.
Due to the restrictions of the phylo or multiphylo format the number of leaves must be at least 2 since there must be at least one edge.

Usage

genETMTree(n)

Arguments

n

Integer value that specifies the desired number of leaves, i.e., vertices with in-degree 1 and out-degree 0.

Value

genETMTree A single tree of class phylo is returned.
