The Eigen sparse matrix only contains the numeric information, it doesn't
contain information like Dimnames that are specific to the R structure. If
you want to access the slots or set their values it is easiest to do that
with the Rcpp::S4 class object.
Of course it helps to use R's str function

Dear all,
I put a sparse "dgCMatrix" into RcppEigen code as a sparse matrix. In Rcpp I
create a new matrix of same dimensions as the input matrix. I would like to
copy the dimnames from the input matrix to the output matrix. Can this be done?
