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.

Changes in RcppArmadillo version 0.9.880.1.0 (2020-05-15)

  • Upgraded to Armadillo release 9.880.1 (Roasted Mocha Detox)

    • expanded qr() to optionally use pivoted decomposition

    • updated physical constants to NIST 2018 CODATA values

    • added ARMA_DONT_USE_CXX11_MUTEX confguration option to disable use of std::mutex

  • OpenMP capability is tested explicitly (Kevin Ushey and Dirk in #294, #295, and #296 all fixing #290).

Courtesy of 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.

If you like this or other open-source work I do, you can now sponsor me at GitHub. For the first year, GitHub will match your contributions.
