Dear List,
I’m having an issue with compiling Rcpp code using ‘fmat’ matrix type on the
server (Linux distro:
CentOS release 5.11 (Final)) and wondering if someone has a quick fix.
Basically, the following code works fine on my Macbook (R 3.2) but not on the
server (Run/sessionInfo pasted).
Any help would be greatly appreciated!
Many thanks,
Yue
Code (test_fmat.cpp):
// -*- mode: C++; c-indent-level: 4; c-basic-offset: 4; indent-tabs-mode: nil;
-*-
// we only include RcppArmadillo.h which pulls Rcpp.h in for us
#include <RcppArmadillo.h>
// [[Rcpp::depends(RcppArmadillo, BH, bigmemory)]]
using namespace Rcpp;
using namespace arma;
// [[Rcpp::export]]
fmat fmatMultiply(fmat x, fmat y)
{
fmat ans = x * y;
return ans;
}
In R:
> sourceCpp('test_fmat.cpp')
