R Documentation

model2sparse: Converts a niche model into a diagonal sparse matrix

Description

model2sparse: Converts a niche model into a diagonal sparse matrix

Usage

model2sparse(model, threshold = NULL)

Arguments

model	A raster object representing the geographic projection of a niche model.
threshold	A threshold to convert a continuous model into a binary model.

Details

threshold parameter represents the suitability value used to convert continuous model into a binary model.

Value

An object of class setA. The niche model is stored as diagonal sparse matrix (slot sparse_model).

Examples

model_path <- system.file("extdata/Lepus_californicus_cont.tif",
                          package = "bamm")
model <- raster::raster(model_path)

sparse_mod <- bamm::model2sparse(model, threshold=0.75)
print(sparse_mod)
raster::plot(sparse_mod@niche_model)
