Hello,
I'd like to be able to simply define functions like this :
SEXP foo( IntegerVector x ){
// .. do something with x
}
instead of this:
SEXP foo( SEXP x){
IntegerVector xx(x) ;
}
and there is something in do_dotcode (I don't know what) that prevents
this. With this file :
=====================
#include <Rcpp.h>
using namespace Rcpp;
extern "C" {
SEXP foo ( IntegerVector x) ;
}
SEXP foo( IntegerVector x ) {
Rprintf( "hello <%p> \n", x.asSexp() ) ;
return x ;
}
=====================
compiled into a so with :
rom...@naxos /tmp $ export PKG_LIBS=`Rscript -e "Rcpp:::LdFlags()"`
rom...@naxos /tmp $ export PKG_CXXFLAGS=`Rscript -e "Rcpp:::CxxFlags()"`
and then :
require( Rcpp)
dyn.load( "foo.so" )
.Call( "foo", 1:10 )
This prints :
rom...@naxos /tmp $ Rscript test.R
Le chargement a nécessité le package : Rcpp
hello <0x100843178>
NULL
but, If I use this file instead:
=====================
#include <Rcpp.h>
using namespace Rcpp;
SEXP foo_( IntegerVector x ) ;
extern "C" {
SEXP foo ( SEXP x ){ return foo_(x) ; }
}
SEXP foo_( IntegerVector x ) {
Rprintf( "hello <%p> \n", x.asSexp() ) ;
return x ;
}
=====================
it works:
rom...@naxos /tmp $ Rscript test.R
Le chargement a nécessité le package : Rcpp
hello <0x102cc0cd8>
[1] 1 2 3 4 5 6 7 8 9 10
In the first case, we are still able to determine the correct function,
otherwise it would not print anything but the object is not correctly
passed through.
Any ideas ?
Romain
