Value

A SpatRaster object, or "Can't access data." if the remote server is unreachable.

Examples

# \donttest{
ras <- get_world_pca()
# Guarded: the function returns a character string when the data
# server is unreachable, so the example also runs offline
if (!is.character(ras)) {
  print(ras)
  terra::plot(ras)
}
