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.

Features

• 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 group-wise frequencies, fidelity and differential species assessment (syntable and synsort functions)
• Heterogeneity-constrained random (HCR) resampling (Lengyel, Chytrý & Tichý, 2011) of community data (hcr_resampling function)
• 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.
