In ibartomeus/fundiv: tools to calculate several functional trait diversity indexes

Description Usage Arguments Value Examples

fdisp measures the functional dispersion (FDis) of a set of communities, as described by Laliberté and Legendre (2010). fdisp_w also allows to weight FDis by biomass

1 2	fdisp_w(d, a, tol = 1e-07, Weigthedby = c("abundance", "biomasCarabids", "biomasBees", "biomassValue"), biomassValue = NA)

`Weigthedby`	character string indicating if should be weighted by 'abundance' or 'biomassValue'. If biomassValue is in "length" units for Carabids or bees, use options 'biomasCarabids' or 'biomasBees' to automatically convert to mass.
`biomassValue`	numerical vector with body weigh (or length) values for each species in the same order as species are provided. It can also be a matrix or data frame with one mass value for each community and species (both communities and species arranged like in a).
`same`	as dbFD

same as dbFD

FDis vector listing the FDis of each community weighted by abundance or biomass

dummy.dist <- gowdis(dummy$trait)
ex1 <- fdisp_w(dummy.dist, dummy$abun, Weigthedby = "biomassValue",
biomassValue = c(1.2, 2.3, 0.6, 1.0, 3.4, 0.2, 1.6, 2.2))
