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
.
