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

     This function is capable of plotting polygons, referenced by its
     id number. These can be filled with colors acording to a given
     variate.

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

     plotpoly(arc,bnd,pal,index=NULL,col, xratio=1, yratio=1,...)

_A_r_g_u_m_e_n_t_s:

     arc: The data returned by a call to get.arcdata

     bnd: The data returned by a call to get.bnddata

     pal: The data returned by a call to get.paldata

   index: IDs of the polygon to be plotted. If it is 'NULL' then all
          the polygons are plotted.

     col: Colors to be used when filling the polygons

  xratio: Controls x-axis ratio. It can take any value from 0 to 1.

  yratio: Controls x-axis ratio. It can take any value from 0 to 1.

     ...: Options to be passed to a call to the function plot when
          creating the display (i. e., window or file).

_V_a_l_u_e:

     Thins function returns nothing, but plots a nice map. :-D
