* Return NA for inconclusive multivariate_change and _difference results (see also vegandevs/vegan#306).

Version 2.0.2
-------------

BUG FIXES

* use codyn::Evar rather than codyn::EQ in RAC_difference
* fixes for breaking change in testthat (PR #111)

Version 2.0.1
-------------

DOCUMENTATION

* use `@inheritParams` to reduce redundancy

BUG FIXES

* elminate unverifiable centroid calculation in vegan::betadisper ([#306](https://github.com/vegandevs/vegan/issues/306))
* better error message (#108)
* fix handling of Null arguments (#95)

-------------

NEW FUNCTIONS

* community_structure: Calculates richness and evenness (using specified metric) for a replicate
* community_diversity: Calculates diversity (using specified metric) for a replicate
* RAC_change: Calculates changes in species richness, evenness, species' ranks, gain, and losses for a replicate over time
* abundance_change: For each species in a replicate, calculates changes in abundance over time
* curve_change: Calculates changes in the shape of the RAC curve for each replicate over time
* multivariate_change: Calculates changes in community composition and dispersion over time
* RAC_difference: Calculates differences in species richness, evenness, species' ranks, shared species between paired samples at a single point in time
* abundance_difference: Calculates differences in abundance for each species in paired samples at a single point in time
* curve_difference: Calculates differences in the shape of the RAC between paired samples at a single point in time
* multivariate_difference: Calculates differences in community composition and dispersion of all replicates between treatments at a single point in time

BUG FIXES
