get1 {permutations}

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
