# linesTorus: Lines and arrows with wrapping in the torus In sdetorus: Statistical Tools for Toroidal Diffusions

## Description

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

## Usage

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

## Arguments

 `x` vector with horizontal coordinates, wrapped in [-π,π). `y` vector with vertical coordinates, wrapped in [-π,π). `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 [-π,π) before plotting.

## Value

Nothing. The functions are called for drawing wrapped lines.

## Examples

 ```1 2 3 4 5 6 7 8``` ```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) ```
