latinRand {randomizationInference}

Random Treatment Assignments for Isomorphic Latin Square Designs

Description

Randomly draws an assignment vector or matrix according to the isomorphic Latin square design, for a specified number of permutations.

Usage

latinRand(w, nrand, row, col)

Arguments

w

a vector or matrix of assignments.

nrand

a number specifying the desired number of random assignments.

row

a vector of row designations.

col

a vector of column designations.

Details

Assignments are randomly permuted along rows and columns such that the Latin square design is preserved.

If w is a matrix, the permutations occur by row.

Value

A list of random isomorphic assignment vectors or matrices.
