Geometric morphometric data and PC scores of the vertebral column a seal

Procrustes aligned 3d landmarks (coord_gpa) and PC scores (scores) of the backbone of Phoca vitulina (ZMUC 160).

Usage

data("seal_gmm")

Format

A list containing: a 3D array of Procrustes aligned 3D landmarks (coord_gpa) of 25 presacral vertebrae with 40 landmarks per vertebra, a matrix of PC scores from a PCA performed on Procrustes aligned landmarks (scores), and a numeric vector with the eigenvalues from the PCA (eigenvals).
