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