as.function.polynom: Coercion to function

In PolynomF: Polynomials in R

Coercion to function

Description

PolynomF objects ARE functions, but this coercion method creates from a polynomial object a pure function with the coefficients fully exposed in the code and which evaluates the polynomial more efficiently.

Usage

## S3 method for class 'polynom'
as.function(x, variable = "x", ...)

## S3 method for class 'polylist'
as.function(x, ...)

Arguments

x	A polynomial object
variable	Character string: what variable name should be used?
...	Additional arguments

Value

An explicit R function evaluating the polynomial

Examples

p <- poly_from_zeros(-2:3)
p
as.function(p)
