Here are some R functions which I have written and used in past studies. Please refer to the original papers for further explanations, citations and context. Each title is linked to my github repository, which can generally be accessed here.
Biotic Novelty Index
Function to calculate the Biotic Novelty Index, as well as a set of R code and data to reproduce the community simulations and the first case study from our 2020 study in Global Change Ecology.

Testing trait distributions in ecological communities
The repository is a toolbox of R functions and workflow for trait-based community ecology that I assembled over the years. I wrote these R functions to test the trait range, trait moments (mean, variance, skewness, kurtosis) and Rao’s quadratic entropy (functional or phylogenetic) within local communities against null models.
