In darunabas/bioregion: an R package for mapping biodiversity and conservation

Description

mapTraits add species trait values to species distribution in geographic space.

Usage

mapTraits(x, trait, FUN = sum, ...)

Arguments

x	A community data object - a vector (with names matching trait data) or a data.frame or matrix (with column names matching names in trait data)
trait	A data.frame of species traits with a column of species names matching species names in the community data, and another column with the trait values.
FUN	The function used to aggregate species trait values in geographic space. By default, if FUN = sum, the sum of all species traits per area or grid cell is calculated.
...	Further arguments passed to or from other methods.
