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 = 100, 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.
