NICHE PARAMETERS

Description

Estimates niche parameters

Usage

niche_parameters(
  x,
  y,
  type = c("region", "global"),
  centroid.w = F,
  rnd.test = F,
  quantile = 0.75,
  np.type = "unimodal",
  np.metric = c("median", "mean", "max"),
  cor = F,
  rep = 100,
  rand = 1,
  alternative = c("greater", "lower")
)

Arguments

`x`	NINA model
`y`	Optional. NINA model
`type`	String indicating the scale of the analysis. Default is "region"
`centroid.w`	logical whether to weight niche overlap by distance to niche centroid
`rnd.test`	Logical to indicate if randomization tests are to be estimated
`quantile`	If `centroid.w` is TRUE, quantle threshold to filter niche densities. Default is 0.5. See `niche_position`
`np.type`	If `centroid.w` is TRUE, type of centroid to estimate. Default is 'unimodal'. See `niche_position`
`np.metric`	If `centroid.w` is TRUE, statistic method to estimate the niche centroid. Default is 'median'. See `niche_position`
`cor`	Logical whether to use environmentally corrected densites
`rep`	Number of random samples to carry out the statistic tests
`rand`	Directions of the comparisons. 1 performs all tests with argument 'x' as base of all comparisons. 2 uses argument 'y'. Default is 1.
`alternative`	String indicating the alternative hypothesis. Default is "greater".
