In goutham1220/shipshape: Intuitive Calculation and Analysis of Procrustes & Elastic Distance Metrics

Description

Adapted from "shapes" package by Ian L. Dryden <[e-mail]>

Usage

shape_proc_distance(x, type = "full", reflect = FALSE)

Arguments

x	3-dimensional array of shapes. Every zth element should be a different shape.
type	string indicating the type of distance; "full" full Procrustes distance, "partial" partial Procrustes distance, "Riemannian" Riemannian shape distance, "sizeandshape" size-and-shape Riemannian/Procrustes distance
reflect	Logical. If reflect = TRUE then reflection invariance is included.

Value

A matrix of all calculated distance. Each distance is labeled by the shapes used for calculation.

bone_1 = bone_shapes[1:100,]
bone_2 = bone_shapes[101:200,]
bone_3 = bone_shapes[201:300,]
bones = array(c(bone_1, bone_2, bone_3), dim = c(100, 2, 3))
shape_proc_distance(bones, type = "full")
