plot.polynomial: Plot Method for Polynomials

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

Plot Method for Polynomials

Description

Plots polynomials, optionally allowing the “interesting” region to be automatically determined.

Usage

## S3 method for class 'polynomial'
plot(x, xlim = 0:1, ylim = range(Px), type = "l",
                len = 1000, ..., xlab = "x", ylab = "P(x)")

Arguments

x	an object of class "polynomial".
xlim	the range to be encompassed by the x axis.
ylim	the range to be encompassed by the y axis.
type	as for plot().
len	number of x points drawn.
...	additional arguments as for plot.
xlab,ylab	graphical parameters.

Details

This is a method for the generic function plot.

A plot of the polynomial is produced on the currently active device. Unless otherwise specified, the domain is chosen to enclose the real parts of all zeros, stationary points and zero itself.
