squarelattice: Square lattice designs

In blocksdesign: Nested and Crossed Block Designs for Factorial and Unstructured Treatment Sets

Description

Internal function constructs square lattice designs for resolvable nested block designs with v*v treatments, r complete replicate blocks and nested blocks of size v.

Returns a simple lattice with r = 2 or a triple lattice with r = 3 for any size of v.

Returns a quadruple lattice with r = 4 for any v <= 30.

Returns a lattice for any r < v + 2 if v is a prime or prime power with p^q less than or equal to:

• 2**12

• 3**7

• 5**5

• 7**4

• (11,13,17,19)**3

• (23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97)**2

Usage

squarelattice(v, r)

Arguments

v	is the required block size and is the integer square root of the required number of treatments
r	is is the required number of replicates
