funrar package
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:

or refer to the CITATION file, using:
citation(package = "funrar")The package is on CRAN, you can install it using:
install.packages("funrar")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)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.
