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) 719 other packages on CRAN.
Conrad released a new upstream version 9.880.1 of Armadillo on Friday which I packaged and tested as usual (result log here in the usual repo). The R package also sports a new OpenMP detection facility once again motivated by macOS which changed its setup yet again.
Changes in the new release are noted below.
