     This world database comes from a thinned cleaned-up version of the
     CIA World Data Bank II data and contains approximately 30,000
     points representing the world coastlines and national boundaries. 
     The full database of nearly 2 million points is found in the
     mapdata package.

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

     data(worldMapEnv)

_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.

     The CIA World Data Bank II is currently (mid-2003) available from 
     <URL: http://www.evl.uic.edu/pape/data/WDB/>.
