latinRand: Permutations of Treatment Assignments for Latin Square Designs

Description

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

Usage

latinRand(w, nperm, row, col)

Arguments

w

a vector or matrix of assignments.

nperm

a number specifying the desired number of random permutations.

row

a vector of row designations.

col

a vector of column designations.

Value

• A list of permuted assignment vectors or matrices.

Details

Assignments are permuted such that the Latin square design is preserved. If w is a matrix, the permutations occur by row.
