linesTorus: Lines and arrows with wrapping in the torus

In egarpor/sdetorus: Statistical Tools for Toroidal Diffusions

Lines and arrows with wrapping in the torus

Description

Joins the corresponding points with line segments or arrows that exhibit wrapping in [-\pi,\pi) in the horizontal and vertical axes.

Usage

linesTorus(x, y, col = 1, lty = 1, ltyCross = lty, arrows = FALSE, ...)

Arguments

x	vector with horizontal coordinates, wrapped in [-\pi,\pi).
y	vector with vertical coordinates, wrapped in [-\pi,\pi).
col	color vector of length 1 or the same length of x and y.
lty	line type as in par.
ltyCross	specific line type for crossing segments.
arrows	flag for drawing arrows instead of line segments.
...	further graphical parameters passed to segments or arrows.

Details

x and y are wrapped to [-\pi,\pi) before plotting.

Value

Nothing. The functions are called for drawing wrapped lines.

Examples

x <- toPiInt(rnorm(50, mean = seq(-pi, pi, l = 50), sd = 0.5))
y <- toPiInt(x + rnorm(50, mean = seq(-pi, pi, l = 50), sd = 0.5))
plot(x, y, xlim = c(-pi, pi), ylim = c(-pi, pi), col = rainbow(length(x)),
     pch = 19)
linesTorus(x = x, y = y, col = rainbow(length(x)), ltyCross = 2)
plot(x, y, xlim = c(-pi, pi), ylim = c(-pi, pi), col = rainbow(length(x)),
     pch = 19)
linesTorus(x = x, y = y, col = rainbow(length(x)), arrows = TRUE)
