rperm | R Documentation |
Function rperm()
creates a word object of random permutations.
Function rcyc()
creates random permutations comprising a single
(group-theoretic) cycle of a specified length (r1cyc()
is a
low-level helper function).

Returns an object of class word
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). You can
control the number of non-fixed elements precisely with argument
len
of function rcyc()
, although this will give only
permutations with a single (group-theoretic) cycle.
