Sum of branch length of a classification dendrogram (Petchey and Gaston, 2002)

Description

Sum of branch length of a classification dendrogram (Petchey and Gaston, 2002)

Usage

	SumBL(traits, gower.dist = TRUE, method.hclust = "average", 
	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.
method.hclust	Define the method for the hclust function (default is "average" i.e. UPGMA).
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 sum of branch length from a classification dendrogram of traits.
