_D_e_s_c_r_i_p_t_i_o_n:

     Interface between GMT 4.0 map-making software and R, enabling the
     user to manipulate geographic data within R and call GMT programs
     to draw and annotate maps in postscript format.

_D_e_t_a_i_l_s:

     _Initialize GMT session:_

       'gmt'  set graphical parameters and postscript file

     _Create a map:_

       'pscoast'  draw
       'psxy'     annotate
       'pstext'   annotate
       'psbar'    annotate
       'psclose'  finalize

     _Convert and calculate:_

       'deg2num'  degrees to numeric
       'geodist'  distance between coordinates

     _Examples:_

       'demo.par', 'demo.coast', 'demo.xy', 'demo.text', 'demo.bar'  strings and data frames that make up a map

     _Internal:_

       'gmt.system', 'r2gmt'  not really intended for the end user

     Additional details are found on the 'help(package="gmt")' page.
