Utilities for array creation

Description

Utilities for array creation

Usage

createAB(s, k = 3, m = NULL, old = FALSE)

BsFromB(B, s = NULL, r = NULL, permlist = NULL, oneonly = TRUE)

BcolsFromBcolllist(Bcollist)

Arguments

s	levels
k	integer; determines the run size: the resulting array will have s^k runs
m	the number of columns to be created
B	n x m matrix
r	number of copies
permlist	permutation list
oneonly	logical: permute all copies in the same way?
Bcollist	list of candidate columns for He et al. (2018) construction

Details

BcolsFromBcolllist tries to create adequate unique matches from a list of suitable matches. For example, if four matches are needed and the list list(1:2, 1:3, 4:6, 1) holds the suitable matches for the four positions, the function would return the vector 2, 3, 4, 1.

Value

createAB returns a list of s^k times m matrices A, B and D for the He, Cheng and Tang (2018) construction

BsFromB returns an rn x m matrix

BcolsFromBcolllist returns column numbers selected for matrix B

Note

BsFromB is currently not used.
