geomorph (version 1.1-3)

Geometric morphometric analysis of 2d/3d landmark data

Description

Read, manipulate, and digitize landmark data, generate shape variables via Procrustes analysis for points, curves and surfaces, perform shape analyses, and provide graphical depictions of shapes and patterns of shape variation
