model2sparse {bamm}

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).

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