plot.density.circular: Plot Method for Kernel Density Estimation for Circular Data

Description

The plot method for density.circular objects.

Usage

## S3 method for class 'density.circular':
plot(x, main = NULL, xlab = NULL, ylab = "Density circular", type = "l", zero.line = TRUE, points.plot = FALSE, points.col = 1, points.pch = 1, plot.type = c("circle", "line"), axes = TRUE, ticks = TRUE, bins, shrink = 1, tcl = 0.025, tol = 0.04, uin, xlim = c(-1, 1), ylim = c(-1, 1), ...)

Arguments

x

an object of class density.circular.

main, xlab, ylab, type

plotting parameters with useful defaults.

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.

axes

logical; if TRUE axis are drawn.

ticks

logical; if TRUE ticks are drawn.

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.

tol

proportion of white space at the margins of plot

uin

desired values for the units per inch parameter. If of length 1, the desired units per inch on the x axis.

xlim, ylim

the ranges to be encompassed by the x and y axes. Useful for centering the plot.

...

futher parameters passed to plot.default.

Value

• None.
