Not quite an answer. I've been using ace() in the acepack library to do _ordinary_ conjoint analysis with rating responses. I never do (nor have any reason to do) choice-based conjoint, so I haven't thought about how to analyze such data, but I'd be interested in the answer if anyone has it. (What would happen if you just use ace() with a binary dependent variable? What if the stimuli are two alternative options rather than one option vs. a constant default?)
