lines.regression.circular: Add a plot for circular regression

In NPCirc: Nonparametric Circular Methods

Add a plot for circular regression

Description

The lines add a plot for regression.circular objects.

Usage

## S3 method for class 'regression.circular'
lines(x, plot.type=c("circle", "line"), points.plot=FALSE, rp.type="p", type="l",
line.col=1, points.col="grey", points.pch=1, units=NULL, zero=NULL,
clockwise=NULL, radial.lim=NULL, plot.info=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.
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.
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. Ignored if plot.info is provided.
clockwise	Logical, indicating the sense of rotation of the plot: clockwise if TRUE and counterclockwise if FALSE. Ignored if plot.info is provided.
radial.lim	The range of the grid circle. Used if plot.type="circle".
plot.info	An object from plot.regression.circular that contains information on the zero, the clockwise and radial.lim. Used if plot.type="circle".
...	Further arguments to be passed to lines.default (if plot.type="line") or to radial.plot (if plot.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).

set.seed(1012)
n <- 100
x <- runif(100, 0, 2*pi)
y <- sin(x)+0.5*rnorm(n)
estNW<-kern.reg.circ.lin(circular(x),y,t=NULL,bw=10,method="NW")
estLL<-kern.reg.circ.lin(circular(x),y,t=NULL,bw=10,method="LL")
res<-plot(estNW, plot.type="circle", points.plot=TRUE)
lines(estLL, plot.type="circle",line.col=2, plot.info=res)
