Thanks very much for this info, Sarah! I have used library(conjoint). Here are the commands used:
library(conjoint) experiment = expand.grid(
+ price = c("low", "medium", "high"),
+ variety = c("black", "green", "red"),
+ kind = c("bags", "granulated", "leafy"),
+ aroma = c("yes", "no"))
design<-caFactorialDesign(data=experiment, type="orthogonal")
Error: could not find function "caFactorialDesign" What could I be missing?
That's hard to say. We need at least the output of sessionInfo() to begin to decide. You've got the reproducible example, but a look at the posting guide might still offer you some advice. Sarah
