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

     Data from the SIC-97 project: Spatial Interpolation Comparison.

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

     data(SIC)

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

     Four objects of the 'class'  '"geodata"': 'sic.all', 'sic.100',
     'sic.367', 'sic.some'. Each is a list with two components:

     '_c_o_o_r_d_s' the coordinates of the data locations. The distance are
          given in kilometers.  

     '_d_a_t_a' rainfall values. The unit is milimeters.  

     '_a_l_t_i_t_u_d_e' elevation values. The unit is milimeters.  

     Additionally an matrix 'sic.borders' with the borders of the
     country.

_S_o_u_r_c_e:

     Data from the project _Spatial Interpolation Comparison 97_; see
