PolynomF (version 2.0-8)

as.function.polynom: 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 polynom
as.function(x, variable = "x", ...)

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

Value

An explicit R function evaluating the polynomial

Arguments

x

A polynomial object

variable

Character string: what variable name should be used?

...

Additional arguments

Examples

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