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.
