In ENMTools: Analysis of Niche Evolution using Niche and Distribution Models

Takes an emtools.species object and adds background points if they're missing. Looks for range raster first, then goes for environmental layers.

Description

Takes an emtools.species object and adds background points if they're missing. Looks for range raster first, then goes for environmental layers.

Usage

check.bg(
  species,
  env = NA,
  nback = 1000,
  bg.source = "default",
  verbose = FALSE,
  bias = NA
)

Arguments

species	An enmtools.species object
env	A SpatRaster containing environmental data.
nback	Number of background points to generate, if any
bg.source	Source for drawing background points. If "points", it just uses the background points that are already in the species object. If "range", it uses the range raster. If "env", it draws points at randome from the entire study area outlined by the first environmental layer.
verbose	Controls printing of various messages progress reports. Defaults to FALSE.
bias	A SpatRaster representing estimated relative sampling bias. Used when bg.source is either "range" or "env".

Value

An enmtools.species object with background points.
