Subject: New Morphometric Software for R
To: [email protected]
Hello all,
We are happy to announce the release of GeoMorph: a morphometrics
package in R for the collection and analysis of landmark-based geometric
morphometric data. It is available on the CRAN package website.
Geomorph provides routines for all stages of a geometric morphometric
analysis. It allows one to read, manipulate, and digitize 2D and 3D
landmark data, generate shape variables via Procrustes analysis for
points, curves and surfaces, perform statistical analyses of shape
variation and covariation, and provide graphical depictions of shapes
and patterns of shape variation.
Most of geomorph's functions are designed for researchers interested in
testing ecological and evolutionary hypotheses of shape variation and
covariation. Methods are available to:
Data
-read existing landmark data files into R (nts, tps, Morphologika format)
-digitize 3D landmarks from surface images within R
-estimate missing landmarks on specimens
Shape
-Superimpose specimens using GPA (for both landmarks and semilandmarks)
Analyses
-Anova/regression designs
-integration/modularity analyses
-analysis of phenotypic trajectories
-assessment of phylogenetic signal for shape data
Visualization
-scatterplots of shapes
-shape deformation plots
-plots of allometric trajectories
-plotting phylogenies in shape space
In the coming months we will add additional functions of interest to
evolutionary biologists.
