In circular: Circular Statistics

Description

Plot an empirical cumulative distribution function for a circular data set.

Usage

## S3 method for class 'ecdf.circular'
plot(x, xlim = c(0, 2 * pi), ylim = NULL,
  xlab = "x", ylab = "Fn(x)", main = NULL, add = FALSE,
  verticals = FALSE, col.01line = "gray70", do.points = (n < 1000),
  pch = 19, col = par("col"), col.points = col, cex.points = par("cex"),
  col.hor = col, col.vert = col, lty = par("lty"), lwd = par("lwd"), ...)

Arguments

x	an object of class ecdf.circular or a numeric vector of class circular.
xlim, ylim	limits for the plot region: see plot.window. Both have sensible defaults if omitted.
xlab, ylab	labels for x and y axis.
main	main title.
add	logical; if TRUE only add to an existing plot.
verticals	logical; if TRUE, draw vertical lines at steps.
col.01line	numeric or character specifying the color of the horizontal lines at y = 0 and 1, see colors.
do.points	logical; if TRUE, also draw points at the (xlim restricted) knot locations. Default is true, for sample size < 1000.
pch	character or integer code; point character if do.points.
col	default color of all points and lines.
col.points	character or integer code; color of points if do.points.
cex.points	numeric; character expansion factor if do.points.
col.hor	color of horizontal lines.
col.vert	color of vertical lines.
lty, lwd	line type and thickness for all lines.
...	further arguments of plot(.), or if(add) segments(.).

Value

A list with two components

t	abscissa (x) values, including the two outermost ones.
y	y values ‘in between’ the t[].
