county_subdivisions: Download a county subdivision shapefile into R
Description
From the US Census Bureau (see link for source, and more information): "All counties and
statistically equivalent entities consist of one or more geographic units that the Bureau
of the Census recognizes as county subdivisions. The two major types of county subdivisions
are minor civil divisions(MCDs) and census county divisions (CCDs).
A State has either MCDs or their statistical equivalents, or CCDs; it cannot
contain both."
