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, bg=NA, 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...
