Welcome to vegan - Community Ecology Package project!
'vegan' is a CRAN package for the analysis of ecological communities. It has tools for analysing ecological diversity, and for the multivariate analysis of communities (NMDS, pCCA, pRDA etc.) - Development on R-Forge discontinued, go to https://github.com/vegandevs/
What is in vegan?
Vegan contains many popular tools used in community ecology. The following list is not exhaustive, but lists only some popular tools:
- Diversity analysis: Shannon, Simpson, Fisher indices, Rényi diversities and Hill numbers.
- Species abundance models: Fisher and Preston models, species abundance distributions.
- Analysis of species richness: species accumulation curves, extrapolated richness.
- Ordination: support and meta functions for NMDS, redundancy analysis, constrained correspondence analysis, constrained analysis of proximities (all three with partial analysis),
- Support functions for ordination: dissimilarity indices, extended dissimilarities, Procrustes analysis, ordination diagnostics, permutation tests.
- Ordination and environment: vector fitting, centroid fitting and smooth surface fitting, adding species scores as weighted averages, adding convex hull, SD ellipses, arrows etc. to ordination.
- Dissimilarity analyses: ANOVA using dissimilarities, ANOSIM, MRPP, BIOENV, Mantel and partial Mantel tests.
- Data standardization: Hellinger, Wisconsin, Chi-square, Beals smoothing.
