[R] Conjoint in R

Hello all, I am trying to apply a conjoint analysis in order to determine the best profile that captures the most preferred combination of levels of given categorical factors. For this a set of factors is given and initially a fractional factorial design has to be produced as a subset of all

Hi, try package MNP for a starting point - which could be used for choice-based-conjoint! And here a paper which show you that a normal Conjoint design is nothing others than a regression analysis, which could ready easy used with little bit programming in R.

Hi, The conf.design package should help you handle the experimental design side of your problem. Depending on your application, it may be unwise to assume that main effects will be enough, as interactions can often turn out to be important (at least in my experience with discrete conjoint).

Another approach, not mentioned yet, is to use ace, in the acepack package. I have used this in an article (with Andy Gurmankin) coming out soon in Memory and Cognition, which I could send by email. It isn't obvious to me that this will (or that it won't) work with a fractional factorial design;
