_D_e_s_c_r_i_p_t_i_o_n:

     This is the default panel function for 'xyplot'. Also see
     'panel.superpose'.  The default panel functions for 'splom' and
     'qq' are essentially the same function.

                  pch = plot.symbol$pch,

_A_r_g_u_m_e_n_t_s:

     x,y: variables to be plotted in the scatterplot

    type: character vector consisting of one or more of the following:
          '"p"', '"l"', '"h"', '"b"', '"o"', '"s"', '"S"', '"r"',
          '"a"', '"g"', '"smooth"'.  If type has more than one element,
          an attempt is made to combine the effect of each of the
          components.

          The behaviour if any of the first six are included in 'type'
          is similar to the effect of 'type' in 'plot' (type '"b"' is
          actually the same as '"o"').  '"r"' adds a regression line
          (same as 'panel.lmline', except for default graphical
          parameters), and '"smooth"' adds a lowess fit (same as
          'panel.loess').  '"g"' adds a reference grid using
          'panel.grid' in the background.  '"a"' has the effect of
          calling 'panel.linejoin', which can be useful for creating
          interaction plots.  The effect of several of these
          specifications depend on the value of 'horizontal'.

          See 'example(xyplot)' and 'demo(lattice)' for examples. 

col, col.line, col.symbol: default colours are obtained from
          'plot.symbol' and 'plot.line' using 'trellis.par.get'. 

font, fontface, fontfamily: font used when 'pch' is a character 

pch, lty, cex, lwd: other graphical parameters. 

     ...: extra arguments, if any, for 'panel.xyplot'. In most cases
          'panel.xyplot' ignores these. For types "r" and "smooth",
          these are passed on to 'panel.lmline' and 'panel.loess'
          respectively. 

horizontal: logical. Controls orientation for certain 'type''s, e.g. 
          one of '"h"', '"s"' or '"S"'

     .

_D_e_t_a_i_l_s:

     Creates scatterplot of 'x' and 'y', with various modifications
     possible via the type argument. 'panel.qq' draws a 45 degree line
     before calling 'panel.xyplot'.

     Note that most of the arguments controlling the display can be
     supplied directly to the high-level (e.g. 'xyplot') call.
