## 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.

### See Also

`plot`, `lines`, `points`, `plot.polynomial`, `lines.polynomial`.

### Examples

    plot(poly.calc(-1:5))
    lines(poly.calc(2:4), lty=2)
    points(poly.calc(-2:6), pch=4)
