[R] Can't Run "Conjoint" Package - Could not find function "caFactorialDesign"?

[Vik Rubenfeld]

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?

Best,


-Vik
