simulate_niche: Simulate niche

In agarciaEE/NINA: Niche Interaction Network Analyses

Simulate niche

Description

Simulates a niche object of class NINA from a former niche or a matrix of environmental coordinates. The function uses ecospat.grid.clim.dyn from ecospat R package to generate the niche object

Usage

simulate_niche(
  z,
  use.whole.env = F,
  method = 1,
  glob = NULL,
  glob1 = glob,
  sample.size = nrow(glob) * 0.1,
  R = 100
)

Arguments

z	m by n matrix indicating the association coefficient (-1 to 1). m are species to be modeled as rows and n interactions as columns
use.whole.env	Logical. Sample from the entire environmental space
method	NINA EN model object for species group two
glob	n by n matrix indicating the competition coefficient between interactions (0 to 1).
glob1	NINA EN model object for species group one
sample.size	String indicating whether to perform at a region or a global level. Note that if models have not been estimated at a region level and it is selected it will produce an error
R	Numeric value indicating independence from biotic associations. Value must be comprised between 0 and 1.

Details

It needs either z or glob arguments to run, otherwise will throw an error

Value

niche object class NINA

Examples

## Not run: 
z <- simulate_niche(glob = cbind(rnorm(100), rnorm(100)))

## End(Not run)
