paleomorph (version 0.1.4)

Geometric Morphometric Tools for Paleobiology

Description

Fill missing symmetrical data with mirroring, calculate Procrustes alignments with or without scaling, and compute standard or vector correlation and covariance matrices (congruence coefficients) of 3D landmarks. Tolerates missing data for all analyses.

Functions in paleomorph (0.1.4)

Fill missing symmetrical landmarks for all specimens in an array using mirrored values from other side of a bilaterally symmetrical object where present

Fill missing landmarks for a single specimen using mirrored values from other side of object

Plot an array of specimen landmark data in an interactive 3D frame

Conducts Procrustes superimposition to align 3D shapes with or without scaling to centroid size.

Calculate 3D vector correlation matrix using the congruence coefficient. Skips any missing values in computation of correlation matrix

Calculate 2d or 3D covariance matrix using unscaled congruence coefficient. Skips any missing values in computation of covariance matrix

Count the number of missing landmarks in an array

Calculate covariance matrix between individual landmark coordinates
