RcppArmadillo 0.10.6.0.0 on CRAN: A New Upstream
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) 882 other packages on CRAN.
This new release gets us Armadillo 10.6.0 which was released yesterday. We did the usual reverse dependency checks (which came out spotless and clean), and had also just done even fuller checks for Rcpp 1.0.7.
Since the previous RcppArmadillo 0.10.5.0.0 release we made a few interim releases to the drat repo. In general, Conrad is a little more active than we want to be with (montly or less frequent) CRAN updates so keep and eye on the drat repo (or follow the GitHub repo) for a higher-frequence cadence. To use the drat repo, use install.packages("RcppArmadillo", repos="https://RcppCore.github.io/drat") or update.packages() with a similar repos argument.
The full set of changes follows. We include the last interim release as well.
