MorphyWeights: Set and get the character weightings associated with a Morphy...

In TreeSearch: Phylogenetic Analysis with Discrete Character Data

Set and get the character weightings associated with a Morphy object.

Description

MorphyWeights() details the approximate and exact weights associated with characters in a Morphy object; SetMorphyWeights() edits them.

Usage

MorphyWeights(morphyObj)

SetMorphyWeights(weight, morphyObj, checkInput = TRUE)

Arguments

morphyObj	Object of class morphy, perhaps created with PhyDat2Morphy().
weight	A vector listing the new weights to be applied to each character
checkInput	Whether to sanity-check input data before applying. Defaults to TRUE to protect the user from crashes.

Value

MorphyWeights() returns a data frame with two named rows and one column per character pattern: row 1, approx, is a list of integers specifying the approximate (integral) weights used by MorphyLib; row 2, exact, is a list of numerics specifying the exact weights specified by the user.

SetMorphyWeights() returns the Morphy error code generated when applying weight.
