Hi. I would like to start using Rcpp modules in my code, but I am having some trouble loading them into R. Here is an example:
#include <Rcpp.h>
template<typename T>
class adding {
public:
const T a, b;
adding(const T&, const T&);
T add2();
};
template<typename T>
adding<T>::adding(const T& a_, const T& b_) : a(a_), b(b_) {}
template<typename T>
T adding<T>::add2() {
T res = a + b;
return(res);
}
RCPP_MODULE(adding){
Rcpp::class_< adding<double> >("adding")
.constructor<double, double>()
.method("add2",&adding<double>::add2)
;
}
Then, in R, I do this:
library(Rcpp)
dyn.load("add.so")
mod <- Module("adding")
mod
The result is:
Uninitialized module named "adding" from package ".GlobalEnv"
I also tried adding a PACKAGE argument, such as PACKAGE = "add.so", to no
avail. So I am wondering if it is possible to use Rcpp modules with
self-compiled code, outside of the R package structure (I believe I have good
reasons for doing this). The library may also include other C++ functions that
are loaded with no problem. It's just the module that is not recognized.
Thanks in advance for any suggestions.
Michael
