An object of class setA showClass("setA")

Slots

niche_model

A RasterLayer or RasterStack representing the environmental suitability model (binary or continuous)

suit_threshold

Numeric value used to binarize continuous models

cellIDs

Numeric vector of raster cell IDs with non-NA values

suit_values

Numeric vector of suitability values for continuous models

sparse_model

A sparse matrix (dgCMatrix) representation of the niche model

Validity

The niche_model slot must be either a RasterLayer or RasterStack.
