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.
