panel.addons {robust} | R Documentation |
This is a utility function used by some of the plotting functions in the Robust Library. It optionally adds a smooth fit using loess, a rugplot, and/or identifies a specified number of extreme observations.
panel.addons(x, y, smooths = FALSE, rugplot = FALSE, id.n = 3, ...)
x |
a numeric vector of x-coordinates. |
y |
a numeric vector of y-coordinates. Must be the same length as x . |
smooths |
a logical value. If TRUE then a smooth fit computed by loess is included in each panel. |
rugplot |
a logical value. If TRUE then a rugplot is included in each panel. |
id.n |
a non-negative integer value specifying the number of extreme points to label in each panel. |
... |
additional arguments are passed to the low-level plotting functions. |
a NULL
value is invisibly returned.
