design.ab: Design in blocks for factorial pxq

Description

It generates a design of blocks for combined pxq. "Random" uses the methods of number generation in R. The seed is by set.seed(seed, kinds).

Usage

design.ab(A, B, r, number = 1, seed = 0, kinds = "Super-Duper")

Arguments

A

Levels of A

B

Levels of B

r

Replications or Blocks

number

Number of first plot

seed

Seed

kinds

Method for to randomize

Value

• A
