Résumé
File List FDind.R -- R source code for indices computation Description The FDind.R R program computes the 3 functional diversity indices presented in Villéger et al. 2008 (Ecology 89:2290–2301), and the functional specialization index proposed by Bellwood et al. 2006 (Proc. R. Soc. B. 273:101–107). Computation requires R libraries « ape » and « geometry » and two matrices as inputs: « traits » (S*T): T traits values for the S species (at least 2 quantitative continuous traits, i.e., numeric values) « abundances » (C*S) : abundances for the S species in C communities (NA allowed) The function returns a dataframe (C*5) with Species richness (Nbsp), functional richness (FRic), functional evenness (FEve), functional divergence (FDiv) and functional specialization (FSpe) values for each of the C communities. A basic example is provided at the end of the script. Details on indices computation are presented in Appendix B.
