我正在尝试在 R 中创建以下田口交叉阵列设计。
Table12.1Inner <- FrF2::FrF2(nruns = 8, generators = "ABC", randomize = FALSE)
Table12.1Outer <- DoE.base::fac.design(nlevels = 2, nfactors=1, factor.names = "E", randomize = FALSE)
Error in fac.design(nlevels = c(4)) :
one factor only is not covered by fac.design
DoE.base::cross.design(Table12.1Inner, Table12.1Outer)
所以我无法创建外部阵列设计。
最佳答案
尝试使用 expand.grid :
expand.grid(A = vals, B = vals, C = vals, D = vals, E.neg = 0, E.pos = 0, y = 0, sdev = 0)
A B C D E.neg E.pos y sdev
1 + + + + 0 0 0 0
2 - + + + 0 0 0 0
3 + - + + 0 0 0 0
4 - - + + 0 0 0 0
5 + + - + 0 0 0 0
6 - + - + 0 0 0 0
7 + - - + 0 0 0 0
8 - - - + 0 0 0 0
9 + + + - 0 0 0 0
10 - + + - 0 0 0 0
11 + - + - 0 0 0 0
12 - - + - 0 0 0 0
13 + + - - 0 0 0 0
14 - + - - 0 0 0 0
15 + - - - 0 0 0 0
16 - - - - 0 0 0 0
