A new upstream release of the Eigen C++ template
library for linear algebra was released a few days ago. And Yixuan Qiu did some
really nice work rolling this into a new
RcppEigen released
and then sent me a nice pull requent. The new version is now on
CRAN, and I will prepare a
Debian in a moment too.
Upstream changes for Eigen are
summarized in their changelog.
On the RcppEigen
side, Yixuan also rolled in some more changes on as()
and
wrap()
converters as noted below in the NEWS
entry.

Rcpp::as()

to “row array”, i.e.,Eigen::Array
