country	Three-letter ISO country code. Corresponding three-letter ISO code for each country can be found in the list_countries dataset.
version	A character vector specifying the GADM version from which to get the geopackage download from. Default is gadm3.6 for current version of GADM.
layer	A numeric value specifying which layer from geopackage to get. A layer corresponds to the different administrative units of the specific country where 1 is country-level.

Value

SpatialPolygonsDataFrame of the specified country map layer.
