Hello,
I have a quick design question. I am working on a program that uses RInside
and RcppEigen, and I want to expose a function back to R. Specifically, I
have a C++ function with the following signature:
double nll_singleton(
const VectorXd& theta,
const MatrixXd& ua,
const Matr

Greetings,
Over the weekend I had wanted to compile an application using RInside and
RCppEigen using icpc. I found the following two pieces of information
helpful.
1. The order of the includes in important. In particular
#include "mpi.h"
#include
#include
#include
mpi.h must be first. If mpi
Hello again,
I am just trying to straighten this out. Say I want to have the exact same
random matrix in C++ as I do in R using rnorm. Is what I am doing below on
the right track?
Thanks,

Thanks for the pointer to sugar.
I was just trying to think of a simple example. So my C++ code will be
essentially:
int main() {
RInside R(argc, argv); // create an embedded R instance
R.parseEval("X = generateSomeMatrix()");
Eigen::MatrixXd Xeigen;
// this is the par
Ah, I see the error. Please disregard this. I see how Rcpp::as works now.

Greetings,
I am new to Rcpp, RInside and the entire family of related packages. I am
experienced with R and also C++ using Eigen but I have never combined the
two before. I would like to create a matrix using R and then play with it
using Eigen. From what I have read so far, it seems like I can us
