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

     Computes the size of the largest connectivity component of the
     graph of 'ncol(distmat)' vertices with edges defined by the
     smallest 'ne' distances.

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

     lcomponent(distmat, ne = floor(3*ncol(distmat)/4))

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

 distmat: symmetric distance matrix.

      ne: integer.

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

     list with components 

      lc: size of the largest connectivity component.

      ne: see above.
