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

     Shrinks a (principal) component towards a simple
     difference-component in 'sca'.

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

     shrinkdiff(zcomp, S, P, criterion)

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

   zcomp: a component vector to be _simplified_.

       S: correlation/covariance matrix

       P: component matrix

criterion: character string specifying the optimality criterion, see
          'sccrit' for details.

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

     a list with the components 

scompmax: a new simple component vector, typically result of
          'simpvector'.

 critmax: the (optimal) value of the criterion, achieved for
          'scompmax'.

_S_e_e _A_l_s_o:
