_D_e_s_c_r_i_p_t_i_o_n:

     After using 'parse.par' and 'model.matrix.multiple', use 
     'set.start' to set starting values for all parameters.  By
     default, starting values are set to 0.  If  you wish to select
     alternative starting values for certain parameters, use
     'put.start' after  'set.start'.

_U_s_a_g_e:

     set.start(start.val = NULL, terms)

_A_r_g_u_m_e_n_t_s:

start.val: user-specified starting values.  If 'NULL' (default), the
          default  starting values for all parameters are set to 0.

   terms: the terms output from 'model.frame.multiple'

_V_a_l_u_e:

     A named vector of starting values for all parameters specified in
     'terms', defaulting to 0.
