rectlattice: Rectangular lattice designs

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

Description

Internal function constructs rectangular lattice designs for resolvable nested block designs with v*(v-1) treatments, r complete replicate blocks and nested blocks of size v.

Returns a rectangular lattice for v*(v-1) treatments and r replicates whenever a square lattice with v*v treatments and r+1 replicates exists; see squarelattice for square lattice designs.

See Cochran and Cox, Experimental Designs, 2nd Edition, Page 417 (Shrikhande method).

Usage

rectlattice(v, r)

Arguments

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