_D_e_s_c_r_i_p_t_i_o_n:

     The 'meuse.grid' data frame has 3103 rows and 2 columns; a grid
     with 40 m x 40 m spacing that covers the Meuse Study area

_U_s_a_g_e:

     data(meuse.grid)

_F_o_r_m_a_t:

     This data frame contains the following columns:

     _x a numeric vector; x-coordinate (see meuse) 

     _y a numeric vector; y-coordinate (see meuse) 

     _d_i_s_t distance to the Meuse river; obtained by a spread (spatial
          distance) GIS operation, from border of river; normalized to
          $[0,1]$ 

     _f_f_r_e_q flood frequency; the lower the value, the larger the flood
          frequency; the origin of this item is questionable

     _p_a_r_t._a arbitrary division of the area in two areas, a and b

     _p_a_r_t._b see 'part.a'

     _s_o_i_l soil type; it is questionable whether these data come from a
          real soil map

_D_e_t_a_i_l_s:

     'x' and 'y' are in RDM, the Dutch topographical map coordinate
     system. Roger Bivand projected this to UTM in the R-Grass
     interface package.
