Description

Computes Gower distance between characters from a phylogenetic data matrix.

Usage

get_gower_dist(x, numeric = FALSE)

Value

The Gower distance matrix.

Arguments

x

A phylogenetic data matrix in Nexus (.nex) format, or in any other data frame or matrix format with a column for each character and terminal taxa as rows, which will be read using ape::read.nexus.data. The data cannot include polymorphisms.

numeric

Whether to treat the values contained in the x as numeric or categorical. If FALSE (default), features will be considered categorical; if TRUE, they will be considered numeric.
