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

I'm trying to run the "Conjoint" package, and I receive the error:

     Error: could not find function "caFactorialDesign"

I'm running R version 2.15.1 on Mac OS X.  I have installed the "Conjoint" package with the "Install Dependencies" checkbox checked. I have clicked the "Update All" button in the R Package Installer.

How can I correct this error?

Thanks in advance to all for any info.

(Please respond to this email address as well as to the list -- Thanks!).

Hi Vik,

You don't need to post to nabble and to the R-help list. Just skip the
nabble step!

Have you loaded the package with:

library(conjoint) # not Conjoint

before you try to use any of its functions?

Thanks very much for this info, Sarah!

I have used library(conjoint). Here are the commands used:
+ price = c("low", "medium", "high"),
+ variety = c("black", "green", "red"),
+ kind = c("bags", "granulated", "leafy"),
+ aroma = c("yes", "no"))
Error: could not find function "caFactorialDesign"

What could I be missing?

Best,

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.

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.

Michael

The function is present in conjoint 1.34, the current version on CRAN.

Rarely do I have to remind respondents to update their installation. :)

Well there you go.

Based on the combined knowledge encapsulated in my and Michael's
earlier replies, the function you're trying to use is present in
conjoint 1.34 and not present in 1.33 so you'll need to upgrade to the
latest version (released 3 August).

I further note that while CRAN has 1.34, the author's website has 1.33.

It looks like 1.34 was uploaded this morning and hasnt made it to my
mirror yet: sorry for the noise.

Vik, it looks like you're in the same boat. Try switching to the
Austrian CRAN master and update -- then it'll be there.

Best,
Michael

I would like to find out how to apply commands found in the bayesm package, to analyze data gathered via a choice-based conjoint study. Is there a web resource where I can seek an R-Project consultant experienced in this, who I could hire to walk me through the appropriate bayesm commands to use for this purpose?

Thanks in advance to all for any info.
