rtensor

template<class T, std::size_t N>
class rtensor : public xt::rcontainer<rtensor<T, N>>, public xcontainer_semantic<rtensor<T, N>> Multidimensional container providing the xtensor container semantics wrapping an R array.
rtensor is similar to the xtensor container in that it has a static dimensionality.
Unlike the rarray container, rtensor cannot be reshaped with a different number of dimensions and reshapes are not reflected on the R side. However, rtensor has benefits compared to rarray in terms of performances. rtensor shapes are stack-allocated which makes iteration upon rtensor faster than with pyarray.
