In marta-vidalgarcia/morpho.tools.GM: A set of functions to help with geometric morphometric analyses of 3D data

morpho.volume

Description

This function returns the volume (and volumes by groups) of a morphospace.

Usage

morpho.volume(x, groups)

Arguments

x	Dataset with three columns (3 dimensions in the morphospace)
groups	An optional factor defining groups

Value

This function returns a list with two objects. The first object is the volume for the whole dataset. If groups have been selected, then it also returns a data.frame with the volumes by group and the percentage of the total volume occupied in the morphospace.
