如何使用 R 中的 FrF2 或 qualityTools 包指定生成器和因子?
How can I specify a generator and factor using the FrF2 or qualityTools package in R?
如何使用 R
中的 FrF2
或 qualityTools
包指定生成器和因子?
小数阶乘experiment是2^{k-p} 其中k=5(因子),p=1,I=ABCD如何生成,其中D因子混淆。因此,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)
控制台:
...
$`generators`
[1] E=ABCD
...
使用 qualityTools 包也没有成功。
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)
答案:
plan2 <- fracDesign(k = 5,
replicates = 1,
gen = "D = ABC")
runOrd(plan2) <- standOrd(plan2)
summary(plan2)
