RcppArmadillo 0.12.4.1.0 on CRAN: New Upstream Bugfix
Armadillo is a powerful and expressive C++ template library for linear algebra and scientific computing. It aims towards a good balance between speed and ease of use, has a syntax deliberately close to Matlab, and is useful for algorithm development directly in C++, or quick conversion of research code into production environments. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 1079 other packages on CRAN, downloaded 29.6 million times (per the partial logs from the cloud mirrors of CRAN), and the CSDA paper) (preprint / vignette) by Conrad and myself has been cited 543 times according to Google Scholar.
This release brings bugfix upstream release 12.4.1 made by Conrad at the end of last week. As usual, I prepared the usual release candidate, tested on the over 1000 reverse depends (which sadly takes a long time on old hardware), found no issues and sent it to CRAN. Where it got tested again and was by a stroke of bad luck upheld for two unrelated issue (one package fell over one of its other dependencies changing a data representation, another fell afoul of a tightened test on total test time) so this awaited the usual email handshake with the CRAN maintainers … and the weekend got in the way. The release also contains a PR kindly provided by Mikael Jagan for an upcoming change in package Matrix.
As a bugfix release, the set of changes is fairly small.
Changes in RcppArmadillo version 0.12.4.1.0 (2023-06-17)
Upgraded to Armadillo release 12.4.1 (Cortisol Profusion Redux)
fix bug in
SpMat::shed_cols()functions such as
.is_finite()andfind_nonfinite()will now emit a runtime warning when compiled in fast math mode; such compilation mode disables detection of non-finite valuesAccommodate upcoming change in package Matrix (Mikael Jagan in #417 addressing #415)
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 Rcpp R-Forge page.
