Question

How can I specify a generator and factor using the FrF2 or qualityTools package in R?

The fractional factorial experiment is 2^{k-p} where k = 5 (factors), p = 1, and I = ABCD how generator, wherein the D factor is confused. Thus, D = ABC.

if(!require("FrF2")) install.packages("FrF2") ; library(FrF2)

plan <- FrF2(nfactors = 5,
         nruns = 16,
         generators = "D=ABC",  # <<<
         replications = 3,
         repeat.only = T,
         randomize = FALSE)
print(plan)

Console:

...

$`generators`
[1] E=ABCD    

...

Using qualityTools package also did not get success.

if(!require("qualityTools")) install.packages("qualityTools") ; library(qualityTools)

plan2 <- fracDesign(k = 5,
               p = 1,
               replicates = 1,
               gen = "D = ABC")
# or gen = c("D = ABC")

runOrd(plan2) <- standOrd(plan2)
print(plan2)

The answer:

plan2 <- fracDesign(k = 5,
                replicates = 1,
                gen = "D = ABC")

runOrd(plan2) <- standOrd(plan2)
summary(plan2)
