In RPS: Resistant Procrustes Superimposition

Description

This function s simply a wrapper for the geomorph function gpagen that performs the classical least squares Procrustes superimposition of the input configurations of landmarks.

Usage

procrustesCM_RPS(X)

Arguments

X	A s-dimensional array (s=2 or s=3) of n x k matrices, representing shapes of k objects through n landmarks in s dimensions

Value

s-dimensional array of n x k matrices, representing shapes of k objects following superimposition.
