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

     Generate particles from the user-specified distribution. This is
     part of the low-level interface, used by 'mif'. This help page
     does not give instruction on how to write a valid 'particles'
     function: see the documentation for 'mif' instead.

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

     particles(object, ...)
     ## S4 method for signature 'mif':
     particles(object, Np = 1, center = coef(object), sd = 0, ...)

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

  object: the 'mif' object

      Np: the number of particles, i.e., number of draws.

  center: the central value of the distribution of particles

      sd: the width of the distribution

     ...: additional arguments.  At present, these are ignored.

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

     The 'particles' method is used to set up the initial distribution
     of particles.  It is an interface to the user-specifed 'particles'
     slot in the 'mif' object.

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

     'particles' returns a list of two matrices.  'states' contains the
     state-variable portion of the particles; 'params' contains the
     parameter portion.  Each has 'Np' columns.
