node.paths {RRphylo}

Tracing nodes along paths

Description

Given a vector of nodes, the function collates nodes along individual lineages from the youngest (i.e. furthest from the tree root) to the oldest.

Usage

node.paths(tree, vec)

Arguments

tree

a phylogenetic tree. The tree needs not to be ultrametric and fully dichotomous.

vec

a vector of node numbers

Value

A list of node paths, each starting from the youngest node (i.e. furthest from the tree root) and ending to the oldest along the path.
