Gabor,
Here is a completely new, second variant of the same example, this time
implemented using only inline with a custom plugin. This should have what
you need.
Code first:

Well I have been releasing within 24 hours of Conrad all along for what must
now be two dozen releases ... so my release wasn't exactly news.

Beautiful Conrad!
This is exactly what helps to make individual random number generation easier
in Armadillo/RcppArmadillo! Up to now I use solely the standard C++ RNG engine
(std::mt19937) and run a loop. Now I can just use .imbue on a matrix and do not
have to care about indices and index bo

Ooops. My bad. So that precludes use of sourceCpp().
All other methods involving the R CMD COMPILE', 'R CMD SHLIB' et

Hi everyone,
In Armadillo 3.800 I've added .imbue(), allowing a matrix to be filled
using a functor or C++11 lambda expression. This allows the use of the
Mersenne twister random number engine built into C++11. For example:
std::mt19937 engine;
std::uniform_real_distribution distr(0.0, 1.0);

run time slows down, and experimenting, it seems it's the cost of
