c++ - How to use RcppEigen -

i beginner of c++, , want add together new bundle "crtrcppeigen" in c++ code rcppeigen, while thing wrong happened when run .bat file. help appreciated.

here c++ code function named "crtrcppeigen" want add together rcppeigen in file 'src':

#include < rcpp.h > #include < rcppeigen.h > #include <eigen/dense> #include <iostream> #include <string> using eigen::matrixxd; using namespace std; using namespace rcpp; using namespace rcppeigen; using namespace eigen; rcppexport sexp matop(sexp xr, sexp yr, sexp kr) { matrixxd x = rcppeigen::as<matrixxd>(xr); matrixxd y = rcppeigen::as<matrixxd>(yr); string k = rcpp::as<string>(kr); int n=x.rows(); int p=x.cols(); int ny=y.cols(); matrixxd i(n,n); i.setidentity(n,n); double sse=(y.transpose()*(i-x*(x.transpose()*x).inverse()*x.transpose())*y).determinant(); if(criteria=="k1") homecoming (wrap(n*log(sse/n)+log(n)*p)); if(criteria=="k2") homecoming (wrap(n*log(sse/n)+(2*p*ny*n+ny*(ny+1))/n-2/n+n+2)); }

here r code in file 'r'

rcppeigen.package.skeleton("crtrcppeigen") getwd() #[1] "c:/users/ljh/documents" crtr <- function(xr,yr,criteriar) { .call('crtrcppeigen',xr,yr,criteriar,package = 'crtrcppeigen') } prompt(crtr)

while when run build crtrcppeigen bundle windows binary.bat, error occurs:

but rcpp bundle under status works. guess wrong c++ code.

your error

crtrcppeigen.cpp:3:20: fatal error: rcpp.h : no such file or directory

which should not happen appear have linkingto: rcpp in description.

to check, did on windows box:

followed direct installation:

as can see works expected suggest compare empty skeleton bundle yours.

fwiw "usually" work on command-line did there looks fine too. said, r path entries @ end , manuals strongly suggest place them @ front.
