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) 757 other packages on CRAN.

Conrad just released a new minor upstream version 9.900.2 of Armadillo which we packaged and tested as usual first as a ‘release candidate’ build and then as the release. As usual, logs from reverse-depends runs are in the rcpp-logs repo.

All changes in the new release are noted below.

Changes in RcppArmadillo version 0.9.900.2.0 (2020-07-17)

• Upgraded to Armadillo release 9.900.2 (Nocturnal Misbehaviour)

  • In sort(), fixes for inconsistencies between checks applied to matrix and vector expressions

  • In sort(), remove unnecessary copying when applied in-place to vectors function when applied in-place to vectors

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.
