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
andracurves
-functions). - Calculation and sorting of synoptic tables with fidelity and differential species assessment (
syntable
andsynsort
functions) - Taxa merging for taxa with identical names (
merge_taxa
- function) - One-step cleaning and transposing of vegetation matrices: (
clean_matrix
andtrans_matrix
- functions) - Conversion between cover-abundance codes and percentage cover (
cov2per
andper2cov
- 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
