# rperm: Random permutations In permutations: The Symmetric Group: Permutations of a Finite Set

## Description

Create a word object of random permutations

## Usage

 `1` ```rperm(n,r,moved=NA) ```

## Arguments

 `n` Number of permutations to create `r` Size of permutations `moved` Integer specifying how many elements can move (that is, how many elements do not map to themselves), with default `NA` meaning to choose a permutation at random. This is useful if you want a permutation that has a compact cycle representation

## Value

Returns an object of class `word`

## Note

Argument `moved` specifies a maximum number of elements that do not map to themselves; the actual number of non-fixed elements might be lower (as some elements might map to themselves).

`size`

## Examples

 ```1 2 3 4 5``` ```rperm(30,9) as.cycle(rperm(30,9)) rperm(10,9,2) ```
