R help - Mar 2013 - How to treat dominant alternatives & infeasible/unrealistic alternatives in the choice set

Please help!

I made an oa design using the DoE package of R.Then, I created the 18 blocks
containing 4 choice sets and converted these into questionnaire form using
rotation method of the CE support package.However,some of the alternatives in
the choice sets are infeasible/unrealistic and dominant (but no attribute
attribute overlapping)

Is there a way to deal with these using R?(such that the statistical properties
of the design are minimallly modified). If can't be done using R, can you
please help me on the best way to deal with these problems?

Thank you very much for your help.
