I was taking a look at this new C++ library, going for Boost review
soon: (or maybe I misunderstood and only the SIMD sub-library is aiming
to be in Boost)

It looks a bit like trying to port Matlab to C++, with an emphasis on

their code preventing us from being able to use it, even though we are
already linked to them.

You are right, now the code compiles! But why?
I understand that data is stored in column major. However I hoped that
using an iterator I would abstract away from how the data is stored
and that the function that increases the iterator takes care of
increasing the pointer of nrow positions...

Hi Ale,
maybe I'm wrong but mat(0,_) is not a NumericVector, but a Rcpp::MatrixRow.
So your function sum() is being called with arguments of the wront type
(the error
message is saying that).
If instead you select a column mat( _, 0) you have a conversion to a
NumericVector.

This is new and perplexing to me. I have an Ubuntu install of r-base,
