     This world database comes from a cleaned-up version of the CIA
     World Data Bank II data and contains approximately 2 million
     points representing the world coastlines and national boundaries. 
     This map is based on latitudes [0, 360), which then has the
     Pacific Ocean in the centre of the map.

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

     data(world2)

_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_MAPDATA_DATA_DIR' for the
     datasets in the mapdata package) is set at package load time.

     The CIA World Data Bank II is currently (mid-2003) available from
