Performs a random permutation of the units for a list of factors and/or variates.
Data to Randomize
Used to enter the names of the variates or factors to be randomized.
The

Available Data.
Seed
Sets the seed for the random number generator. A value of 0 will use a
random seed generated from the system clock, if this is the first use of
the generator; otherwise it will continue the sequence previously used.
If the seed is taken from the system clock a message will be produced
in the output indicating its value, allowing it to be re-used.
Any particular non-zero integer seed will always produce the same underlying
sequence of pseudo-random numbers to use in determining the permuted order,
so the seed should normally be set to 0 except when you wish to exactly repeat
an earlier randomization.
