design.youden: Incomplete Latin Square Design

Description

Such designs are referred to as Youden squares since they were introduced by Youden (1937) after Yates (1936) considered the special case of column equal to number treatment minus 1. "Random" uses the methods of number generation in R. The seed is by set.seed(seed, kinds).

Usage

design.youden(trt, r, serie = 2, seed = 0, kinds = "Super-Duper",first=TRUE
,randomization=TRUE)

Value

parameters: Design parameters
sketch: Design sketch
book: Fieldbook

Arguments

trt: Treatments
r: Replications or number of columns
serie: number plot, 1: 11,12; 2: 101,102; 3: 1001,1002
seed: seed
kinds: method for to randomize
first: TRUE or FALSE - randomize rep 1
randomization: TRUE or FALSE - randomize
