...ly not an operation or function on SWX.RET. So how do I get a reference to this object? #include <stdio.h> #include <R.h> #include <Rinternals.h> #include <Rdefines.h> #include <Rembedded.h> int main(int argc, char** argv) { SEXP e,c,portSpec,portData,portConstr,portVal,tsAssets; int errorOccurred,nx,ny,i,j; double *v; const char *x,*y; Rf_initEmbeddedR(argc, argv); // loading fPortfolio PROTECT(e = lang2(install("library"), mkString("fPortfolio"))); R_tryEval(e, R_GlobalEnv, NULL); UNPROTECT(1); // creat...

...Unfortunately I cannot figure out how to do this from C. Here is what I wrote so far: #include <stdio.h> #include <R.h> #include <Rinternals.h> #include <Rdefines.h> #include <Rembedded.h> int main(int argc, char** argv) { SEXP e,c,portSpec,portData,portConstr,portVal,portWeights,tsAssets,tsReturns,nAssets,reciprocal; int errorOccurred,nx,ny,i,j; double *v; const char *x,*y; Rf_initEmbeddedR(argc, argv); // loading fPortfolio PROTECT(e = lang2(install("library"), mkString("fPortfolio"))); R_tryEval(e, R_GlobalEnv...
