CharacterLength: Character length

In TreeSearch: Phylogenetic Analysis with Discrete Character Data

Character length

Description

Homoplasy length of each character in a dataset on a specified tree.

Usage

CharacterLength(tree, dataset, compress = FALSE)

FitchSteps(tree, dataset)

FastCharacterLength(tree, dataset)

Arguments

tree	A tree of class phylo.
dataset	A phylogenetic data matrix of phangorn class phyDat, whose names correspond to the labels of any accompanying tree.
compress	Logical specifying whether to retain the compression of a phyDat object or to return a vector specifying to each individual character, decompressed using the dataset's index attribute.

Value

CharacterLength() returns a vector listing the contribution of each character to tree score, according to the algorithm of \insertCiteBrazeau2018;textualTreeTools.

Functions

• FastCharacterLength(): Do not perform checks. Use with care: may cause erroneous results or software crash if variables are in the incorrect format.
