In SOAs: Creation of Stratum Orthogonal Arrays

Strong Orthogonal Arrays of Strength t using the method of Liu and Liu

Description

Strong Orthogonal Arrays of Strength t using the method of Liu and Liu

Usage

OSOA_LiuLiut(oa, t = NULL, m = NULL, permlist = NULL, random = TRUE)

Arguments

oa	matrix or data.frame that contains an ingoing symmetric OA. Levels must be denoted as 0 to s-1 or as 1 to s.
t	strength of oa. If NULL (default), t will be determined. t can be chosen smaller than the input strength if additional columns are desired.
m	desired number of columns. Defaults to the maximum possible.
permlist	a list of length m of lists of length 1 of permutations of the levels
random	a logical (a random draw of permutations is used if permlist is NULL)

Details

Suitable OAs for argument oa can e.g. be constructed with OA creation functions from package lhs or can be obtained from arrays listed in R package DoE.base.

Value

an orthogonal array
