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)

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

Details

kinds <- c("Wichmann-Hill", "Marsaglia-Multicarry", "Super-Duper", "Mersenne-Twister", "Knuth-TAOCP", "user-supplied", "Knuth-TAOCP-2002", "default" )

Value

`parameters`	Design parameters
`sketch`	Design sketch
`book`	Fieldbook
