add.tip.random: Add tips at random to the tree

In vanderleidebastiani/daee: Data Analysis for Ecology and Evolution

Description

Function to add new tip at random to a tree with branch length. This function is a small change in the function add.random, see details.

Usage

add.tip.random(tree, tip, method = "length")

Arguments

tree	phylogeny as an object of class "phylo".
tip	tip name for the added.
method	The method to add the new tip, partial match to "equal" or "length". See details (Default method = "length").

Details

This function is a small change in the function add.random allowing add only one tip at random only in ultrametric phylogenetic tree. Two methods are available. The method "length" add the tip with probability equivalent to edge length, long edge have more probability than short edge. The method "equal" each edge has equal probability to receive the new tip.

Value

The phylogeny as an object of class "phylo" with new tip.
