[R] Conjoint in R

[christian schulz]

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.
