| panel.smooth {graphics} | R Documentation |
An example of a simple useful panel function to be used as
argument in e.g., coplot or pairs.
panel.smooth(x, y, col = par("col"), bg = NA, pch = par("pch"),
cex = 1, col.smooth = "red", span = 2/3, iter = 3,
...)
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. |
coplot and pairs where panel.smooth
is typically used;
lowess which does the smoothing.
pairs(swiss, panel = panel.smooth, pch = ".")# emphasize the smooths pairs(swiss, panel = panel.smooth, lwd = 2, cex= 1.5, col="blue")# hmm...
