United States State Boundaries Map

Description

This database produces a map of the states of the United States mainland generated from US Department of the Census data (see the reference).

Usage

data(stateMapEnv)

Format

The data file is merely a character string which specifies the name of an environment variable which contains the base location of the binary files used by the map drawing functions. This environment variable (R_MAP_DATA_DIR for the datasets in the maps package) is set at package load time if it does not already exist. Hence setting the environment variable before loading the package can override the default location of the binary datasets.
