Hi, Alessandro,
I have confirmed and reproduced your error.
It should be a bug and it is in
https://github.com/RcppCore/Rcpp/blob/master/inst/include/Rcpp/vector/MatrixColumn.h#L39
In your case, i and n both are integers, but i * n caused an overflow. We
will fix this soon.
Thank you for the te

Oh noes. install_gitub() is not what one should use when we have drat.
I just rolled the Rcp
I got another error when using the Matrix.column() function, as in the
code below:
#include
#include "array.cpp"
// [[Rcpp::export]]
Rcpp::IntegerMatrix makeMat(int nrow=18, int ncol=136633572){
Rcpp::IntegerMatrix mat(nrow, ncol);
for (int i = 0; i < ncol; ++i) {
As Sean O'Riordain correctly pointed out, I used the install_github
command improperly. Doing
devtools::install_github("RcppCore/Rcpp")
works and the big matrix is allocated correctly.
Thanks for the help and for the great work you are doing!

It's great that R and Rcpp have support for long vectors! that makes
my life so much easier!
So I installed Rcpp version 0.12.1 and the error is still there (see
end of the email). If I interpret the commit history correctly, the
commit that fixes the bug was done shortly after the 0.12.1 release
The bug is probably fixed by this commit:

Dear All,
When creating a large matrix with the follwing code:
