lexicographicPermutation: Generate the n:th lexicographic permutation of a vector

In HenrikBengtsson/R.basic: [R] Class Library - Stand-alone basic functions [DEPRECATED]

Description

Generate the n:th lexicographic permutation of a vector. The 0:th permutation is the non-permuted vector. The last permutation is the (n-1):th. If the vector is of length N, there are N! permutation.

Usage

## Default S3 method:
lexicographicPermutation(x, n, ...)

Arguments

x	The vector from which the permutation should be generated.
n	An integer between 0 and N!-1, where N is the length of the vector. If n==0 the non-permutated vector is returned.
...	Not used.

Value

Returns a permuted vector of the same length as the input vector.
