linearMrca: Linear MRCA function

In treespace: Statistical Exploration of Landscapes of Phylogenetic Trees

Linear MRCA function

Description

Function to make the most recent common ancestor (MRCA) matrix of a tree, where entry (i,j) gives the MRCA of tips i and j. The function is linear, exploiting the fact that the tree is rooted.

Usage

linearMrca(tree, k = 0)

Arguments

tree	an object of the class phylo which should be rooted.
k	(optional) number of tips in tree, for faster computation

Examples

## generate a random tree
x <- rtree(6)

## create matrix of MRCAs: entry (i,j) is the node number of the MRCA of tips i and j
linearMrca(x,6)
