The data can be loaded using
exdat_pwm_1 <- terra::rast(
system.file("extdata", "exdat_pwm_1.tif", package = "healthiar")
)
(see Examples section below).
When loaded it is a variable of class SpatRaster, which contains air pollution exposure levels
of municipalities in the Brussels-Capital region (Belgium).
Because it is a .tif file it is stored in the package's inst/extdata directory.
