Shift oritin

Description

These small convenience functions shift polynomials by relocating the origin to a new position. The primary function is generic and active methods are provided for polynom and polylist objects.

Usage

## Default S3 method:
change.origin(p, o, ...)
## S3 method for class 'polynom'
change.origin(p, o, ...)
## S3 method for class 'polylist'
change.origin(p, o, ...)

Arguments

Details

The function change.origin.default is a trap for unimplemeted methods.

Value

A polynom or polylist object with the origin shifted to 0.

Examples

x <- polynom()
p <- 1 - 2*x + x^2
change.origin(p, 1)
## x^2
