# length: Various vector-like utilities for permutation objects.

## Description

Various vector-like utilities for permutation objects such as
`length`

, `names()`

, etc

## Usage

# S3 method for word
length(x)
# S3 method for permutation
length(x) <- value
# S3 method for word
names(x)
# S3 method for word
names(x) <- value

## Arguments

value

In function `names<-.word()`

, the new names

## Details

These functions have methods only for word objects; cycle objects use
the methods for lists. It is easy to confuse the *length* of a
permutation with its `size`

.

It is not possible to set the length of a permutation; this is more
trouble than it is worth.

## Examples

# NOT RUN {
x <- rperm(9,5)
names(x) <- letters[1:9]
data(megaminx)
length(megaminx) # the megaminx group has 12 generators, one per face.
size(megaminx) # the megaminx group is a subgroup of S_129.
names(megaminx) <- NULL # prints more nicely.
megaminx
# }
