hadaPar {randomizeR}R Documentation

Representing Hadamard Randomization

Description

Represents the randomization procedure Hadamard Randomization.

Usage

hadaPar(N, groups = LETTERS[1:2])

Arguments

N

integer for the total sample size of the trial.

groups

character vector of labels for the different treatments.

Details

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.

Value

S4 object of the class hadaPar.

Note

getProb and getAllSeq are currently only supported for hadaPar with total sample size N=12.
