\title{Points Method for Polynomials}
\description{
Add a polynomial to an existing plot usually as a point plot.
}
\usage{
\method{points}{polynomial}(x, length = 100, \dots)
}
\arguments{
\item{x}{an object of class \code{"polynomial"}.}
\item{length}{size of x vector at which evaluations are to be made.}
\item{\dots}{additional arguments as for the points generic.}
}
\details{
This is a method for the generic function \code{\link{points}}.
Points representing the given polynomial are added to an existing
plot. Values outside the current plot region are not shown.
