Default Panel Function for xyplot

Description:

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

Usage:

     panel.xyplot(x, y, type="p",
                  pch = plot.symbol$pch,
                  col,
                  col.line = plot.line$col,
                  col.symbol = plot.symbol$col,
                  font = plot.symbol$font,
                  fontfamily = plot.symbol$fontfamily,
                  fontface = plot.symbol$fontface,
                  lty = plot.line$lty,
                  cex = plot.symbol$cex,
                  lwd = plot.line$lwd, ...)
     panel.splom(...)
     panel.qqmath(...)
     panel.qq(...)

Arguments:

     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", "smooth"'. 

          The behaviour if any of the first six are included in 'type'
          is similar to the effect of 'type' in 'plot'.  '"r"' adds a 
          regression line (same as 'panel.lmline', except for default
          graphical parameters), and '"smooth"' adds a lowess fit (same
          as 'panel.loess').

          See example in 'xyplot' for an example. 

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. 

Details:

     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 'xyplot' call.
