rase (version 0.3-2)

tree.slice:

Description

Identifies the branches in a phylogenetic tree that the slice intersects with. It is used by rase.slice.

Usage

tree.slice(tree, slice)

Arguments

tree

phylogenetic tree of class "phylo".

slice

the time at which to slice. It should be in the same units of the phylogenetic tree.

Value

returns a matrix where each row is an intersecting branch with the following columns: two integers associating the branch (i.e., ancestor, descendant), the age of the ancestral node, and the age of the descendant node.

Details

The tree must be fully dichotomous and all the tips should be extant lineages (time = 0).
