rarray

template<class T>
class rarray : public xt::rcontainer<rarray<T>>, public xcontainer_semantic<rarray<T>>

Multidimensional container providing the xtensor container semantics to an R array.

rarray is similar to the xarray container in that it has a dynamic dimensionality. Reshapes of a rarray container are reflected in the underlying R array.
