Because we are not sure if those features are actually useful, we would prefer to take a "quick and dirty" approach just to try them out. The additional feature is that in every iteration of the algorithm membership-probabilities should by calculated by a multinomial logit or probit model. We have tried to get C/C++ code for this, but sadly neither me nor my collegue succeded in obtaining C-code for something, which has certainly already be programmed in C several times.

So I have actually two questions: Is it feasible to use R-code and R-functions like "multinom" within a c++ program? And if so, what is the best way to implement this (how to get data from C into the R functions, how to execute the R functions within C++, how to transfer the results back to c++)?

Hi,

For a quick (and pretty not dirty) approach, try Rserve : http://rosuda.org/Rserve/
