I tried with Rcpp::NumericMatrix but I have segmentation fault :-( This is probably because I'm learning C++ just now...and I don't know how to deal with pointers and so on...
If you want help, you are going to need to provide some more details.
I don't know how to declare NumericMatrix in my objects... if I do it I have segfault...
What did you do ?
How can I send you the source archive ? Is it possible to attach them in ML ?
You can attach files. However, please trim your code to something small that maintains the problem. I'm not interested in debugging entire applicatons ... not for free anyway ;-)

I'm a newbie :-D Something self contained I can compile on my machine and that shows the error you see. I ran the tests and everything seems to go fine with their compilation and execution. I can't see any errors, only "good" output from R and C++. That's good news. It means we really need to see your example. About the vector< vector<double> > I'm trying to set a matrix instead of a list of vectors because the source of our portfolioBenchmark function needs that kind of data type. Do you have to store it as a vector< vector<double> > ? Can't you use, e.g. a Rcpp::NumericMatrix ?

They should all work on released pairs of Rcpp + RInside -- it is part of our testing.
