Description

A SpatialPolygonsDataFrame containing polygons for the 23 counties in the state of Wyoming.

Usage

data("WY")

Format

A SpatialPolygonsDataFrame containing 23 polygons whose union outline boundaries of the state of Wyoming. Source of the Shapefile containing all US counties in 2015 was https://www.census.gov/geo/maps-data/data/cbf/cbf_counties.html.

	min	max
x	495506	1084419
y	4538294	5006162
