Simulate species habitat suitability data

Generates simulated species data using Gaussian random fields.

Usage

simulate_species(x, n = 1, scale = 0.5)

Arguments

x

terra::rast() object to use as a template.

n

integer value denoting the number of layers to simulate. Defaults to 1.

scale

numeric value denoting the level of spatial auto-correlation in the simulated data. Defaults to 0.5.

Value

A terra::rast() object with values between zero and one.

# simulate data for 4 species
spp <- simulate_species(r, 4)

# plot simulated species
plot(spp, main = "simulated species distributions", axes = FALSE)
