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) * Calculation and sorting of synoptic tables with calculation of fidelity and differential species (syntable() and synsort() functions)
Furthermore some basic functions are included, such as standard error of the mean sem() and coefficient of variance cv().
