Hi Dirk,
thanks for the fast reply. It seems, that using ints is the only possibility here. I
understand though, that the arma::umat has type 'unsigned int', hasn't it? So in this
case I wouldn't be able to use umat, but rather mat<int>, right?
Which is arma::imat
See http://arma.sourceforge.net/docs.html#Mat
Best

R itself has no unsigned integers (just as it has no [signed or unsigned] short
or long integeger).
You should be able to write wrappers though, but this MUST entail copies for
that very reason. So maybe stick to ints?
