ouchDescendants {surface}

Obtain Descendants from an ouch Tree

Description

Identifies the nodes and tip taxa descended from a given ancestor in an ouchtree or hansentree object. Used to test whether two ‘convergent’ regimes are actually nested when randomly placing regime shifts in a Hansen model in the function surfaceSimulate

Usage

ouchDescendants(node, otree)

Arguments

node

Which node in the ouchtree object to identify the descendants of

otree

An ouchtree object

Value

A vector of integers corresponding to the descendents (integers match the @nodes element of the ouchtree)
