Represents the randomization procedure Hadamard Randomization.
hadaPar(N, groups = LETTERS[1:2])integer for the total sample size of the trial.
character vector of labels for the different treatments.
S4 object of the class hadaPar.
Hadamard randomization has been proposed by R.A. Bailey. The key idea is to
use the columns of a special Hadamard Matrix as a randomization scheme. The
implemented algorithm uses the Hadamard Matrix with N=12 columns
proposed in the paper, see references.
