orbit: Orbits of integers

Description

Finds the orbit of a given integer

Usage

orbit_single(c1,n1)
orbit(cyc,n)

Value

Given a cyclist c1 and integer n1, function

orbit_single() returns the single cycle containing integer

n1. This is a low-level function, not intended for the end-user.

Function orbit() is the vectorized equivalent of

orbit_single().

Arguments

c1,n1

In (low-level) function orbit_single(), a cyclist and an integer vector respectively

cyc,n

In (vectorized) function orbit(), cyc is coerced to a cycle, and n is an integer vector

Examples

orbit(megaminx,13)


# orbit() is vectorized:
x <- cycle(list(list(a=1:2,4:6,8:10)))
orbit(x,1:10)
