In leung-lab/s2bak: Fit species distribution models for multiple using the S2BaK framework.

Simulate example data for fitting SDMs and S2BaK

Description

This function simulates the data needed for fitting SDMs for multiple species including generated trait and environments. The function is to primarily to illustrate the data structure, as well as demonstration of the package functions.

Usage

s2bakSim(
  species = 30,
  sites = 3000,
  surv = 300,
  minimum.sightings = 30,
  env.prob = c(0.5, 1),
  trait.prob = c(0.5, 1),
  max.iter = 100
)

Arguments

species	numeric. The number of species used for fitting
sites	numeric. The number of environment sites in the dataset for species sightings
surv	numeric. The number of survey sites
minimum.sightings	numeric. The function will re-generate a new species until the minimum number of sightings (and survey presences) is greater than or equal to the provided value.
env.prob	numeric vector of size two for the range of probabilities for establishment given environment
trait.prob	numeric vector for the range of probabilities for establishment given species trait
max.iter	numeric. Number of attempts to generate a given species if the number of presences is less than the minimum.

Value

a list of data.frames for the environment of the sightings, the environment of the surveys, species traits, species sightings, and the survey presences.
