Explore the spatial distribution of occurrence and background points

Usage

explore_calibration_geo(data, raster_variables, plot = TRUE)

Arguments

data: an object of class prepared_data returned by the prepare_data() function.
raster_variables: (SpatRaster) predictor variables used for model calibration.
plot: (logical) wheter to plot the SpatRaster. Default is TRUE.
...: additional arguments passed to terra::plot().

Value

A categorical SpatRaster with four factor values representing:

1 - Background cells
2 - Presence cells
3 - Cells with both presence and background
4 - Non-used cells

Examples

# Import raster layers
var <- terra::rast(system.file("extdata", "Current_variables.tif",
                               package = "kuenm2"))

# Import occurrences
data(sp_swd, package = "kuenm2")

# Explore calibration data
pbg <- explore_calibration_geo(data = sp_swd, raster_variables = var[[1]])
