add_edge_length: Assign and compute edge lengths from a sample of trees

In phangorn: Phylogenetic Reconstruction and Analysis

Assign and compute edge lengths from a sample of trees

Description

This command can infer some average edge lengths and assign them from a (bootstrap/MCMC) sample.

Usage

add_edge_length(tree, trees, fun = function(x) median(na.omit(x)),
  rooted = all(is.rooted(trees)))

Arguments

tree	a phylogenetic tree or splitnetwork where edge lengths are assigned to.
trees	an object of class multiPhylo, where the average for the edges is computed from.
fun	a function to compute the average (default is median).
rooted	rooted logical, if FALSE edge lengths is a function of the observed splits, if TRUE edge lengths are estimated from height for the observed clades.

Value

The tree with newly assigned edge length.
