Points Method for Polynomials

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

# 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.
