[R] optFederov/AlgDesign - help avail?

[zubin]

Hello, we are needing to generate optimal (Fractional) designs for 
discrete choice applications, where we will be using logistic regression 
or multinomial logit as the modeling technique.

It looks like optFederov, in the AlgDesign package may work, but not 
sure if this algorithm works when the variable of interest is binary or 
nominal? 

Anyone who are experts in this area, anyone interested in consulting 
with us in this topic (if so, email me we can arrange)? 

Or can confirm/deny optFederov can work in the discrete case?

thx!
