ouchDescendants: 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)
Value
A vector of integers corresponding to the descendents (integers match the @nodes element of the ouchtree)
Arguments
node
Which node in the ouchtree object to identify the descendants of
otree
An ouchtree object
