fixed: Fixed elements

In permutations: The Symmetric Group: Permutations of a Finite Set

Fixed elements

Description

Finds which elements of a permutation object are fixed

Usage

## S3 method for class 'word'
fixed(x)
## S3 method for class 'cycle'
fixed(x)

Arguments

x	Object of class word or cycle

Value

Returns a Boolean vector corresponding to the fixed elements of a permutation.

Note

The function is vectorized; if given a vector of permutations, fixed() returns a Boolean vector showing which elements are fixed by all of the permutations.

This function has two methods: fixed.word() and fixed.cycle(), neither of which coerce.
