MinMaxMSTR Documentation

Ratio of the shortest distance to the longest distance in a minimum spanning tree

Description

Ratio of the shortest distance to the longest distance in a minimum spanning tree.

Usage

	MinMaxMST(traits, gower.dist = TRUE, scale.tr = TRUE, method.dist = "euclidian")

Arguments

traits

Traits matrix (traits in column)

gower.dist

Calculate gower distance using the function gowdis from package FD.

scale.tr

Does traits need to be scale before multi-traits metric calculation? Only use when gower.dist = FALSE. Default is yes.

method.dist

Method to calculate the distance in case of multi-traits metric (function dist). Only use when gower.dist = FALSE. Default is euclidian.

Value

The value of the ratio of the shortest distance to the longest distance in a minimum spanning tree.
