Software using R

These programs perform various types of morphometric analyses using R, a free software environment for statistical computing and graphics. Documentation and the R software can be downloaded from the R project website at http://www.r-project.org/.

Analysis of Ecological Data : Exploratory and Euclidean methods in Environmental sciences. Contains commands for Procrustes fitting. Daniel Chessel, Anne-Beatrice Dufour and Stephane Dray, with contributions from Jean R. Lobry, Sebastien Ollier, Sandrine Pavoine and Jean Thioulouse.

Aligns a 3D specimen along the midline plane without size scaling and fills in missing data by reflecting the other side. The result includes both sides without averaging (“aligned”). It also provides the deviations from the plane of symmetry for the midline landmarks ("errors"). Developed by Annat Haber (University of Chicago).

Aligns a 3D specimen along the midline plane without size scaling and averages the left and the right. The result includes the midline landmarks and one set of the lateral ones (“aligned”). It also provides the deviations from the plane of symmetry for the midline landmarks ("errors") and the differences between left and right equivalent landmarks (“asymmetry”). Developed by Annat Haber (University of Chicago).”.

The shapes package is a set of procedures for statistical shape analysis in R. Includes functions for Bookstein baseline registration for 2D data, GPA for 2 and higher dimensional data, plotting of shapes, and other functions. Index file listing the main functions. By Ian Dryden. Version 1.0-7.
