OA2LHD {LHD}

Transfer an Orthogonal Array (OA) into an LHD

Description

OA2LHD transfers an OA into an LHD with corresponding size

Usage

OA2LHD(OA)

Arguments

OA

An orthogonal array matrix.

Value

If the input is logical, then the output will be an LHD whose sizes are the same as input OA. The assumption is that the elements of OAs must be positive.

Examples

#create an OA(9,2,3,2)
OA=matrix(c(rep(1:3,each=3),rep(1:3,times=3)),ncol=2,nrow=9,byrow = FALSE);OA

#Transfer the "OA" above into a LHD according to Tang (1993)
