Create a word object of random permutations

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

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

Returns an object of class `word`

# NOT RUN { rperm(30,9) as.cycle(rperm(30,9)) rperm(10,9,2) # }
