lines.polynomial: Lines Method for Polynomials

Description

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

Usage

# S3 method for 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.
