get1

Retrieve particular cycles or components of cycles

Description

Given an object of class cycle, function get1() returns a representative of each of the disjoint cycles in the object's elements. Function get_cyc() returns the cycle containing a specific element.

Usage

get1(x,drop=TRUE)
get_cyc(x,elt)

Arguments

`x`	permutation object (coerced to `cycle` class)
`drop`	In function `get1()`, argument `drop` controls the behaviour if `x` is length 1. If `drop` is `TRUE`, then a vector of representative elements is returned; if `FALSE`, then a list with one vector element is returned
`elt`	Length-one vector interpreted as a permutation object
