Hm. That it not desirable so maybe we can do better, but you should also note
that you are using the list type in a suboptimal way by growing
Hi,
For a Rcpp::List object, the attributes got lost say if I add another

When poking around internal Armadillo pointers and arrays for sparse

longer than specified by the Compressed Sparse Column (CSC) format.
