I'm new to the group, to rcpp and to C++ also :-P
I'm trying to embed R in a little program which loads a txt file, parses it
into an object and calls a function developed by our R coders.
What I aim to do is to move one of our actual Java procedures (built on
Java/Rserve architecture) to C++/RInside/Rcpp, I think we could have lot of
improvements in this way.
This is a snippet of the procedure:
R["nav_in"] = Rcpp::wrap(input.nav);
R["cashFlows_in"] = Rcpp::wrap(input.cashFlows);
R["dates_in"] = Rcpp::wrap(input.dates);
R["indexesBmk_in"] = Rcpp::wrap(input.indexesBmk);
R["weightsBmk_in"] = Rcpp::wrap(input.weightsBmk);
R["benchmark_in"] = Rcpp::wrap(input.benchmark);
R["datesBmk_in"] = Rcpp::wrap(input.datesBmk);
R["creationDate_in"] = Rcpp::wrap(input.creationDate);
R["activationDate_in"] = Rcpp::wrap(input.activationDate);
R["finalDate_in"] = Rcpp::wrap(input.finalDate);
R["start_in"] = Rcpp::wrap(input.start);
R["type_in"] = Rcpp::wrap(input.type);
string evalstr = "res <- portfolioBenchmark(nav_in, cashFlows_in,
dates_in, indexesBmk_in, weightsBmk_in, benchmark_in, datesBmk_in,
creationDate_in, activationDate_in, finalDate_in, start_in, type_in); res";
res = R.parseEval(evalstr);
What I obtain is the following:
Errore in .Call("R_isMethodsDispatchOn", onOff, PACKAGE = "base");
Numero di argomenti errato (2), ce ne vogliono 1 per
terminate called after throwing an instance of 'Rcpp::binding_not_found'
what(): binding not found: '.AutoloadEnv'
Excuse for the message, which is an Italian/English mix...
What is this error about ? And then... the result of the
"portfolioBenchmark" function should be a list..How can I convert the
returned SEXP res into a list ?
Thanks in advance,
