View source: R/overlap_profile.R

Compute profiles of Hill numbers-based spatial overlaps from multiple Environmental Niche Model projection rasters.

1	overlap_profile(raster, qvalues, metric, threshold)

`raster`	A RasterStack (multiple projections) object containing ENM projections with suitability scores.
`qvalues`	A vector of sequential orders of diversity (default from 0 to 5). qvalues=seq(from = 0, to = 5, by = (0.1))
`metric`	A vector indicating the similarity metrics to be computed. Default: metric=c("C","U","V","S")
`threshold`	Suitability value(s) below which all values are converted into zeros. If a RasterStack (multiple projections) is used, the argument should contain a vector of threshold values.

Spatial overlap profile computation based on Hill numbers

A vector of breadth values at different orders of diversity or a matrix containing breadth values at different orders of diversity (columns) per projection (rows).
