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

_U_s_a_g_e:

     data(stateMapEnv)

_F_o_r_m_a_t:

     The data file is merely an assignment to 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.
