In RPS: Resistant Procrustes Superimposition

Description

This function obtains the individual resistant-symmetric shape for 2D object-symmetry data. The input is an array A of size n (landmarks) x p (dimensions) x k (objects) Landmarks must be in this order: saggital (or unpaired) landmarks first, then left paired landmarks and finally right paired landmarks. Configurations are ordered in this way: L side Object 1 and R side Object 1, L side Object 2 and R side Object 2, etc

Usage

objectsymm_RPS(A,ctr="gmedian",prs.file,proj.met="msum",legend.loc="topleft")

Arguments

A	Input data: an array or matrix of size n (landmarks) x 2 (in 2D) x k (objects)
ctr	Centering options: "gmedian" (the spatial or gemetric median, default choice), "median" (the componentwise median), "mean" (the average)
prs.file	This is a .txt file indicating the L+R paired landmarks as rows: e.g. 7 15; 8 16; etc.
proj.met	The choice to compute the saggital axis: sum or median of projections
legend.loc	The location of the legend for the plot.result function

Value

w
