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

     This function fits a variogram model to spatial data and
     calculates some statistics.

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

     varobj(m, iter = 50, tolerance = 2e-04, trace = 1, loo = F)

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

       m: n by 3 matrix with spatial data

    iter: this argument is put forward to the optimization routine

tolerance: this argument is put forward to the optimization routine

   trace: if set to values higher than 1 some debug messages are given

     loo: if set to TRUE, leave-one-out residuals are clculated

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

     Only spherical variogram models are fitted.

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

     a variogram object
