Functions for Community Data and Ordinations
A collection of functions useful in (vegetation) community analyses
and ordinations. The ordination functions work as an addition to the
functions from the vegan-package.
Includes: * Automatic species selection for ordination diagrams based
on cover abundances and species fit (ordiselect - function)
* Generation of species response curves (specresponse -
function) * Scree/stress plots for NMDS (screeplot_NMDS -
function) * Rank-abundance curve plotting for single or multiple samples
(racurve and racurves-functions). *
Calculation and sorting of synoptic tables with fidelity and
differential species assessment (syntable and
synsort functions) * Taxa merging for taxa with identical
names (merge_taxa - function) * One-step cleaning and
transposing of vegetation matrices: (clean_matrix and
trans_matrix - functions) * Conversion between
cover-abundance codes and percentage cover (cov2per and
per2cov - functions)
Furthermore some basic functions are included, such as standard error
of the mean sem, coefficient of variance cv or
conversion between degrees and radians
deg2rad/rad2deg.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
