funrar is a package to compute functional rarity indices, it quantifies how species are rare both from a functional and an extent point of view. Following the different facets of rarity proposed by Rabinowitz (1981). See this reference for more details on Functional Rarity indices:

If you want to have the latest development version use remotes:
# install.packages("remotes") # If 'remotes' is not installed yet
remotes::install_github("Rekyt/funrar", build_vignettes = TRUE)
Example vignettes
In addition to code example included in help of functions, two vignettes explain how to use the package. The
functional rarity indices vignette explains
in details the different indices and function provided; while the
sparse matrices vignette shows how to use
sparse matrices to gain speed in memory when computing functional rarity indices.
Access the vignette through R using the vignette() abd browseVignettes() functions.
