lines.density.circular: Add a Plot for Kernel Density Estimation for Circular Data

Description

The lines add a plot for density.circular objects.

Usage

## S3 method for class 'density.circular':
lines(x, type = "l", zero.line = TRUE, points.plot = FALSE, points.col = 1, points.pch = 1, plot.type = c("circle", "line"), bins, shrink = 1, tcl = 0.025, ...)

Arguments

x

an object of class density.circular.

type

plotting parameter with useful default.

zero.line

logical; if TRUE, add a base line at $y = 0$. Used when plot.type is "line".

points.plot

logical; if TRUE original data are added to the plot.

points.col, points.pch

parameters used to draw the points.

plot.type

type of the plot.

bins

number of ticks to plot.

shrink

parameter that controls the size of the plotted circle. Default is 1. Larger values shrink the circle, while smaller values enlarge the circle.

tcl

length of the ticks.

...

futher parameters passed to lines.default.

Value

• None.
