Hello R-devel, I want to write extensions for R in C (maybe C++ and Fortran later) and it works fine, but there is one problem, which I cannot solve (in my view).
I want to handle a matrix from R in C. For arrays there is "as.double(...)", but nothing for a matrix. I searched a while, but didn't find something. Last I looked at the source code of e1071 and of the core itself and recognized (I hope I understood this), that you (and the "e1071" people) use "as.double()" and give ".C" an array and one have to "parse" the matrix again in the C function. This sounds a little complicate. Isn't there another way? A more adapted way? Greetings Wilm ps: I joined the R-devel list, but didn't get an confirmation mail. I hope this is normal -- ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
