RcppArmadillo 0.10.7.3.0 on CRAN: Bugfix, New Features
Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 928 other packages on CRAN.
I somehow missed to blog and tweet about the recent release based on the Armadillo 10.7.3 upstream release. Conrad is in “long-term support mode”, and 10.7.* is meant to provide fixes and stability relative to the most recent release which we did on September 30. We did actually find a regression when checking reverse-dependencies requiring an upstream move to 10.7.3. At the same time, we folded pull request #352 in. It addresses an old bug of ours where Armadillo fields types were not converted correctly in all dimensions.
So no we do have 0.10.7.3.0 on CRAN, as well as 0.10.7.3.1 with the (opt-in) field) fixes on the drat repo) repo. As the change perturbs a few existing packages, it is opt-in for now. We will likely aim at a proper deprecation of the old behaviour and give packages time to adjust. Stay tuned.
With that, big thanks to Jonathan Berrisch for filing issue #351 and basically addressing it in pull request #352. Very nice work, and I basically just wrapped a few more tests around it.
The full set of changes (since the last CRAN release 0.10.7.0.) follows.

Courtesy of my CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
