RcppArmadillo 0.10.2.1.0: New Upstream Release
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) 823 other packages on CRAN.
This release brings us Armadillo 10.2 with a few updates as detailed below in the list of changes. Upstream release 10.2 was made a couple of days ago, but we need to balance new upstream updates with a responsible release cadence at CRAN. As we needed a maintenance release in early January, I opted to wait four weeks with this one which hence gets us 10.2.0 and 10.2.1 at once. As tweeted (with a follow-up) it had yet another very smooth passage at CRAN so we again appreciate the excellent work of the CRAN maintainers and say Thank You!.
Anybody who desires more frequent updates show look at the RcppCore drat repo which provides more frequent interim updates. Here for example we also had 0.10.2.0.0 available for your testing pleasure.
Also of note is that here is now a Python variant pyarma for those who might want enjoy Armadillo with Python.
The full set of changes follows.
