permutations (version 1.0-9)

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

x

permutation object

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
