_D_e_s_c_r_i_p_t_i_o_n:

     These are predefined prepanel functions available in Lattice.

_U_s_a_g_e:

     prepanel.lmline(x, y, ...)
     prepanel.loess(x, y, ...)
     prepanel.qqmathline(y, distribution,
                         f.value = ppoints,
                         p = c(0.25, 0.75), 
                         ...) 

_A_r_g_u_m_e_n_t_s:

    x, y: x and y values, numeric or factor

distribution: quantile function for theoretical distribution. This is
          automatically passed in when this is used as a prepanel
          function in 'qqmath'. 

 f.value: as used in 'qqmath'

       p: numeric vector of length two, representing probabilities.
          Corresponding quantile pairs define the line used. 

     ...: other arguments

_V_a_l_u_e:

     usually a list with components 'xlim', 'ylim', 'dx' and 'dy', the
     first two being used to calculate panel axes limits, the last two
     for banking computations.  The form of these components are
     described under 'xyplot'.  There are also several undocumented
     prepanel functions that serve as the default for high level
     functions, e.g., 'prepanel.default.xyplot'

     further options to 'prepanel.loess'
