RcppArmadillo on CRAN: Bugfixes

armadillo image

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) 937 other packages on CRAN, and downloaded over 22 million times (per the partial logs from the cloud mirrors of CRAN).

This release brings another bug fix release 10.7.5 by Conrad in the ‘long-term support’ 10.7.* series we started with on September 30. As the bug fixes can come a little quicker than the desired monthly cadence CRAN aims for, we skipped a few of those release for CRAN only but of course still provide them via the Rcpp drat repo.

The full set of changes (since the last CRAN release follows. It includes the nice fixes to the fields type mentioned right after the last release.

Changes in RcppArmadillo version (2021-12-16)

  • Upgraded to Armadillo release 10.7.5

    • fix aliasing bug in diagmat()

    • fix detection of 2x2 triangular matrices

Changes in RcppArmadillo version (2021-11-23)

  • Upgraded to Armadillo release 10.7.4

    • faster handling of diagonal matrices by inv_sympd(), pinv(), rank()

    • more robust detection of incorrect data format by .load()

  • Correct dimensions setting in import/export of arma::field types, protected by #define (Jonathan Berrisch in #352 fixing #351)

  • Add unit tests for fields both with and without new #define (Dirk)

Courtesy of my 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.
