Functions for Community Data and Ordinations
A collection of functions useful in (vegetation) community analyses and ordinations. The ordination functions work as add-on for functions from vegan-package.
Includes: * Automatic selection of species for ordination diagrams using limits for cover abundances and/or species fit (ordiselect() - function) * Species response curves (specresponse() - function) * Stress/scree plots for NMDS (dimcheckMDS() - function) * Rank-abundance curves (racurve() and racurves() - functions; the latter for (multiple) samples)
Furthermore some basic functions are included, such as standard error of the mean sem() and coefficient of variance cv().
