fyshuffle: Fisher-Yates shuffle

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.

Value

A randomized version of the input vector.

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).
