Hi,
This has to be a basic question, but I cannot figure out what I am missing nor
see quite similar pre-existing posts.
I am trying to create an Rcpp module around a class (generated C++ proxy
class). The environment is Rcpp 0.10.5 on Windows, R 3.0.2 x64 and RTools 3.0.
R CMD INSTALL spits the dummy at compilation(?) time when the Exporter things
kick in, with the message " cannot convert 'SEXP' to 'const
std::vector<double>*' in initialization" on the 'Play' method as per below.
class SimulationExport {
public:
SimulationExport();
~SimulationExport();
void Execute(void);
void Play(const char* name, const std::vector<double>* values);
// other methods snipped
}
RCPP_MODULE(SimulationEx){
class_<SimulationExport>( "Simulation" )
// snipped
.method( "play", &SimulationExport::Play)
// snipped
}
I don't get why it cannot wrap a vector<double> given how similar it is to
"7.2.2.7 Full Example" in the " Seamless R and C++ Integration with Rcpp" book.
The same sample code created with Rcpp.package.skeleton compiles (though it
fails check on load, BTW). The only difference is the presence of a 'const'
modifier before the vector, but removing it does not solve the issue.
Rcpp.package.skeleton('sampleRcpp', module=TRUE, author='J-M')
library(devtools)
check('sampleRcpp') # passes past the compilation step.
Cheers,
J-M
