In polynom: A Collection of Functions to Implement a Class for Univariate Polynomial Manipulations

Lines Method for Polynomials

Description

Add a polynomial to an existing plot usually as a line plot.

Usage

## S3 method for class 'polynomial'
lines(x, len = 1000, xlim = NULL, ylim = NULL, ...)

Arguments

x	an object of class "polynomial".
len	size of vector at which evaluations are to be made.
xlim, ylim	the range of x and y values with sensible defaults.
...	additional arguments as for the lines generic.

Details

This is a method for the generic function lines.

Lines representing the given polynomial are added to an existing plot. Values outside the current plot region are not shown.
