library(terra)
## RasterLayer objects
files <- system.file("maps", package = "quickPlot")
files <- dir(files, full.names = TRUE, pattern = "tif")
maps <- lapply(files, function(x) terra::rast(x))
names(maps) <- sapply(basename(files), function(x) {
strsplit(x, split = "\\.")[[1]][1]
})
layerNames(maps)
## SpatVector objects
caribou <- terra::vect(cbind(x = stats::runif(1e2, -50, 50),
y = stats::runif(1e2, -50, 50)))
