getExtant {phytools}R Documentation

Returns a list of the extant or extinct lineages in a tree containing non-contemporaneous tips

Description

The function getExtant takes a tree as input and returns a vector containing the names of all the tips that have a height above the root that is equal (to a degree of numerical precision determined by tol) to the height of the highest tip. getExtinct returns the complement.

Usage

getExtant(tree, tol=1e-8)
getExtinct(tree, tol=1e-8)

Arguments

tree

a phylogeny stored as an object of class "phylo" with some tips that are non-contemporaneous (i.e., end before the present).

tol

a tolerance value to account for numerical imprecision.

Value

A vector with the tip names of extant or extinct species in the tree.
