Simple Panel Plot

Description:

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

Usage:

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

Arguments:

     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'.

See Also:

     'coplot' and 'pairs' where 'panel.smooth' is typically used;
     'lowess'.

Examples:

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