_D_e_s_c_r_i_p_t_i_o_n:

     An example of a simple useful 'panel' function to be used as
     argument in e.g., 'coplot' or 'pairs'.

_U_s_a_g_e:

     panel.smooth(x, y, col = par("col"), bg = NA, pch = par("pch"),
                  cex = 1, col.smooth = "red", span = 2/3, iter = 3,
                  ...)

_A_r_g_u_m_e_n_t_s:

    x, y: numeric vectors of the same length

col, bg, pch, cex: numeric or character codes for the color(s), point
          type and size of 'points'; see also 'par'.

col.smooth: color to be used by 'lines' for drawing the smooths.

    span: smoothing parameter 'f' for 'lowess', see there.

    iter: number of robustness iterations for 'lowess'.

     ...: further arguments to 'lines'.

_S_e_e _A_l_s_o:

     'coplot' and 'pairs' where 'panel.smooth' is typically used;
     'lowess' which does the smoothing.

_E_x_a_m_p_l_e_s:

     pairs(swiss, panel = panel.smooth, pch = ".")# emphasize the smooths
     pairs(swiss, panel = panel.smooth, lwd = 2, cex= 1.5, col="blue")# hmm...
