plot.regression.circular: Plot circular regression

In NPCirc: Nonparametric Circular Methods

Plot circular regression

Description

The plot method for regression.circular objects.

Usage

## S3 method for class 'regression.circular'
plot(x, plot.type=c("circle", "line"), points.plot=FALSE, rp.type="p", type="l",
line.col=1, points.col="grey", points.pch=1, xlim=NULL, ylim=NULL,
radial.lim=NULL, xlab=NULL, ylab=NULL, labels=NULL, label.pos=NULL, units=NULL,
zero=NULL, clockwise=NULL, main=NULL, ...)

Arguments

x	An object of class regression.circular.
plot.type	Type of the plot: "line": linear plot, "circle": circular plot.
points.plot	Logical; if TRUE original data are added to the plot.
rp.type, type	Character indicating the type of plotting. Default type="l" and rp.type="p".
line.col	Color code or name.
points.col	Color code or name for the original data. Used if points.plot=TRUE.
points.pch	Plotting 'character', i.e., symbol to use for the original data. Used if points.plot=TRUE.
xlim, ylim	The ranges to be encompassed by the x and y axes. Used if plot.type="line".
radial.lim	The range of the grid circle, used if plot.type="circle".
xlab, ylab	Titles for the x axis and y axis, respectively.
labels	Character or expression vector of labels to be placed at the label.pos. label.pos must also be supplied.
label.pos	Vector indicating the position (between 0 and 2π) at which the labels are to be drawn.
units	Units measure used in the plot. If NULL the value is taken from the attribute of object 'x' from the argument 'x', i.e. x$x.
zero	Where to place the starting (zero) point, i.e. the zero of the plot. If NULL the value is taken from the attribute of object 'x' from the argument 'x', i.e. x$x
clockwise	Logical, indicating the sense of rotation of the plot: clockwise if TRUE and counterclockwise if FALSE. If NULL the value is taken from the attribute of object 'x' from the argument 'x', i.e. x$x
main	An overall title for the plot.
...	Further arguments to be passed to plot.default (if plot.type="line") or to to radial.plot (if codeplot.type="circle" and x is the output of kern.reg.circ.lin) or to lines3d (if plot.type="circle") and x is the output of kern.reg.circ.circ).

Value

If plot.type="circle" and x is the output of kern.reg.circ.lin), this function returns a list with information on the plot: zero, clockwise and radial.lim.
