# cable.lines: Overlay Bent Cable On Existing Plot In bentcableAR: Bent-Cable Regression for Independent Data or Autoregressive Time Series

## Description

A user-specified bent cable is added to an existing plot. Its intended use is for superimposing a bent-cable regression fit to a scatterplot of the data. The transition is marked by vertical lines at τ and τ\pmγ.

## Usage

 1 cable.lines(x, theta, col = "black", lwd = 1, lty = 2, fit.lty = 1) 

## Arguments

 x A numeric vector of design points or the range of these design points on the existing scatterplot. theta A vector of bent-cable coefficients, in the form of c(b0,b1,b2,tau,gamma). col, lwd Graphical parameters for plotting the bent-cable function and transition. lty Graphical parameter for marking the transition. fit.lty Graphical parameter of type lty for plotting the bent-cable function.

## Note

This function is intended for internal use by bentcable.ar.
