outside a package) this does not happen.

And FWIW he used confirmed over IM that devtools sets NDEBUG. So there --
devtools issues, not an Rcpp or RcppEigen issue.

|
| -----------------------------------------------------------------------------
|
| #include <RcppEigen.h>
|
| using namespace Rcpp;
|
| using Eigen::Map;
| using Eigen::VectorXd;
| using Eigen::RowVectorXd;
| using Eigen::MatrixXd;
|
| // [[Rcpp::depends(RcppEigen)]]

| // but at the same time much, much shorter and more readable
| //
| // The following 'tag' ensure determinant2() is accessible from R
| //
| // [[Rcpp::export]]
| int determinant2(int S, Map<MatrixXd> Ineq) {
|
| VectorXd thetaTMP = Rcpp::as<VectorXd>(rbeta(S, 0.5, 0.5));
| RowVectorXd theta = thetaTMP.transpose();
|
| VectorXd IneqT = (theta*Ineq.transpose());
|
| return 0;
| }

| Ineq <- structure(0, .Dim = c(1L, 1L)) #error
| oneSample2(Sx = S, Ineq = Ineq)
| }
|
| no_trigger <- function() {
| S <- 3
| Ineq <- structure(c(-1, 1, 0), .Dim = c(1L, 3L)) # no error
| oneSample2(Sx = S, Ineq = Ineq)
| }
|
| no_trigger() # no issue
| trigger() # no issue either
| */
|
| -----------------------------------------------------------------------------
|
|

|
| -----------------------------------------------------------------------------
| R> Rcpp::sourceCpp("~/Dropbox/tmp/henrik.cpp")

| + Ineq <- structure(c(-1, 1, 0), .Dim = c(1L, 3L)) # no error

| + }
|
| R> no_trigger() # no issue
| [1] 0
|
| R> trigger() # no issue either
| [1] 0
| R>
| -----------------------------------------------------------------------------

|
| There is what we could call a user error. Or if you wish a design error. You
