Can't Run "Conjoint" Package - Could not find function "caFactorialDesign"?
With conjoint_1.33 and rather up to date dependencies, I don't see caFactorialDesign and neither does getAnywhere(). Vik, do you have a citation that suggests this function exists? The closest I find is gen.factorial() in the AlgDesign package. The findFn function in the sos library might also be of help here. Best, Michael

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 -- Sarah Goslee http://www.functionaldiversity.org
