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

     Return a matrix evaluating reproducing kernels for the discrete
     shrinkage towards zero or the mean estimate

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

     shrink0(x, y=x)
     shrink1(x, y=x)

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

       x: a vector of numerical values or factor indicating different
          levels.

       y: a vector of numerical values or factor indicating different
          levels. Default is x.

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

     a matrix with the numbers of row and column equal to the length of
     x and y respectively.  The [i, j] element is the reproducing
     kernel evaluated at the ith element of x and jth element of y.

     'shink0' shrinks towards zero, and 'shrink1' shinks towards the
     mean.
