fyshuffle: Fisher-Yates shuffle

In fgpt: Floating Grid Permutation Technique

Description

Function to shuffle vectors according to the Fisher-Yates procedure

Usage

fyshuffle(x)

Arguments

x	Vector containing the sequence which needs to be shuffled. This vector can be of any type and it is allowed to have one element.

Details

Other than the sample function fyshuffle treats a single value as a vector with one element and will therefore return this element as the shuffled version of the original vector (which are similar).

Value

A randomized version of the input vector.
