niche_overlap: Niche Overlap

In agarciaEE/NINA: Niche Interaction Network Analyses

Niche Overlap

Description

Estimates the proportion of niche overlap between two niche objects of class NINA. The function uses the Schoener's D metric with an optional implementation that weights niche differences in base to the proximity to the niche centroid of the first argument.

Usage

niche_overlap(
  x,
  y,
  cor = F,
  centroid.w = F,
  type = "unimodal",
  method = "median",
  quantile = 0.95
)

Arguments

x	NINA niche object
y	NINA niche object
cor	Logical whether to use environmentally corrected densites
centroid.w	logical whether to weight niche overlap by distance to niche centroid
type	If centroid.w is TRUE, type of centroid to estimate. Default is 'unimodal'. See niche_position
method	If centroid.w is TRUE, statistic method to estimate the niche centroid. Default is 'median'. See niche_position
quantile	If centroid.w is TRUE, quantle threshold to filter niche densities. Default is 0.5. See niche_position

Value

Numeric value indicating the proportion of niche overlap between two niches
