A new RcppEigen release 0.3.3.3.0 was put into CRAN (and Debian) a few days ago. It brings Eigen 3.3.* to R.
Once again, Yixuan Qiu did most of the heavy lifting over a multi-month period as some adjustments needed to be made in the package itself, along with coordination downstream.
The complete NEWS file entry follows.
Updated to version 3.3.3 of Eigen
Fixed incorrect function names in the examples, thanks to Ching-Chuan Chen
The class MappedSparseMatrix<T> has been deprecated since Eigen 3.3.0. The new structure Map<SparseMatrix<T> > should be used instead
Exporters for the new type Map<SparseMatrix<T> > were added
Travis CI is now driven via run.sh from our forked r-travis
Courtesy of CRANberries, there is also a diffstat report for the most recent release.
