edgeProbs {phytools} | R Documentation |
Compute the relative frequencies of state changes along edges
Description
Computes the relative frequencies of character state changes along edges from a sample of stochastically mapped character histories.
Usage
edgeProbs(trees)
Arguments
trees |
an object of class |
Details
The function assumes that all trees in the sample differ only in their mapped histories & not at all in topology or branch lengths.
Note that edgeProbs
only asks whether the starting and ending states of the edge differ in a particular way, and thus ignores multiple-hits along a single edge.
Value
The object that is returned is a matrix with the state changes & the relative frequency of each state change. Rows are in the order of the matrix edge
for any of the mapped trees.
