panel.smooth {graphics}

R Documentation

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 = 2, 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 which does the smoothing.

Examples

pairs(swiss, panel = panel.smooth, pch = ".")  # emphasize the smooths
pairs(swiss, panel = panel.smooth, lwd = 2, cex = 1.5, col = 4)  # hmm...
