Calculate the weighted endemism for species present in raster data.
Arguments
- x
SpatRaster. A SpatRaster containing presence-absence data (0 or 1) for a set of species. The layers (species) will be sorted according to the tree order. See the phylo.pres function.
- inv.R
SpatRaster. Inverse of range size. See
inv.range- filename
character. Output filename
- ...
additional arguments passed for terra::app
