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, sub=NULL, xlab=NULL, ylab="Density circular", type="l",
  zero.line=TRUE, points.plot=FALSE, points.col=1, points.pch=1, 
  points.cex=1, plot.type=c("circle", "line"), axes=TRUE, ticks=FALSE, 
  bins=NULL, offset=1, shrink=1, tcl=0.025, tcl.text = 0.125, sep=0.025, tol=0.04, 
  digits=2, cex=1, uin=NULL, xlim=NULL, ylim=NULL, join=FALSE, nosort=FALSE, 
  units=NULL, template=NULL, zero=NULL, rotation=NULL, 
  control.circle=circle.control(), ...)

Arguments

`x`	an object of class `density.circular`.
`main, sub, 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, points.cex`	parameters used to draw the points.
`plot.type`	type of the plot: "line": linear plot, "circle": circular plot.
`axes`	logical; if `TRUE` axis are drawn.
`ticks`	logical; if `TRUE` ticks are drawn.
`bins`	number of ticks to plot.
`offset`	the radius of the circle
`shrink`	parameter that controls the size of the plotted function. Default is 1.
`tcl`	length of the ticks.
`tcl.text`	The position of the axis labels.
`sep`	constant used to specify the distance between stacked points. Default is 0.025; smaller values will create smaller spaces.
`tol`	proportion of white space at the margins of plot
`digits`	number of digits used to print axis values.
`cex`	point character size. See help on `par`.
`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.
`join`	logical: should the first and the last point joined.
`nosort`	logical: should the data sort before plotting. Defaults is to sort.
`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$x`.
`template`	template used in the plot. If `NULL` the value is taken from the attribute of object 'x' from the argument 'x', i.e. `x$x`.
`zero`	position of the zero used in the plot. If `NULL` the value is taken from the attribute of object 'x' from the argument 'x', i.e. `x$x`.
`rotation`	rotation used in the plot. If `NULL` the value is taken from the attribute of object 'x' from the argument 'x', i.e. `x$x`.
`control.circle`	parameters passed to `plot.default` in order to draw the circle. The function `circle.control` is used to set the parameters.
`...`	futher parameters passed to `plot.default`.

Value

A list with information on the plot: zero, rotation and next.points.
