Points Method for Polynomials
Description
Add a polynomial to an existing plot usually as a point plot.
Usage
## S3 method for class 'polynomial'
points(x, length = 100, ...)
Arguments
x |
an object of class "polynomial" .
|
length |
size of x vector at which evaluations are to be made.
|
... |
additional arguments as for the points generic.

Details
This is a method for the generic function points .
Points representing the given polynomial are added to an existing
plot. Values outside the current plot region are not shown.
