Thanks Dirk, but i'm not asking for this either.
The code worksonly it doesn't time the same.
My question is: is it normal -- is there an
overhead in using rcpp and how large is it,
typically?

Hi Steve,
Timing:
i use:
int start_s=clock();
..
..
int stop_s=clock();
cout << "time: " << (stop_s-start_s)/double(CLOCKS_PER_SEC)*1000 << endl;
Function:
Whatever it is, it's coming from these three functions (when i uncoment them,
the rest of the code runs in comparable speed).

Hi all,
the same code when timed in cpp (i.e. without any interfacing with R)
runs about 2 times faster than when called from R and timed from R's
system.time(). In this type of overhead normal or is it a sign i'm doing
something not optimally?

Hi all,
i have a compiling cpp code that i want
to use in R.
NumericMatrix Rcpp_x(R_x);
Map x(Rcpp_x.begin(),n,p);
is there a way, with rcpp, to map R_x to a MatrixXf object?
Best,
___
