Thanks again, Dirk.
full example (sorry for the verbose post):
library(inline)
library(Rcpp)
inc <- '
#include
#include
#include
using namespace arma;
using namespace cppbugs;
class TestModel: public MCModel {
public:
const mat& y; // given
const mat& X; // given
Normal b;

Hello all,
I need to convert a std::string to a RAWSXP. I think i know hot do to this
without Rcpp. It goes something like this (i haven't tested this):
SEXP stringToRaw(std::string x) {
SEXP y;
PROTECT(y = allocVector(RAWSXP, x.length()));
memcpy(RAW(y
Not sure that I saw the original posting from Vinh but it may be
helpful to know that there is an example that uses Rcpp classes to do
much of packaging of the function, arguments, initial values, etc. in
the minqa package
