fundiversity: a modular R package to compute functional diversity indices

Functional diversity is widely used and widespread. However, the main packages to compute functional indices are not flexible adapted volume of data in modern ecological analyses. We here present fundiversity, an R package that eases computation classical indices. It leverages parallelization memoization (caching results memory) maximize efficiency with thousands columns rows. also did a performance comparison provide analog functions. In addition being more flexible, fundiversity was always order magnitude quicker than alternatives. aims be lightweight, efficient tool indices, which can variety contexts. Because it has been designed following clear principles, easy extend. hope wider community will adopt we welcome all contributions.
