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) 685 other packages on CRAN.

A new upstream release 9.850.1 of Armadillo was just released. And as some will undoubtedly notice, Conrad opted for an increment of 50 rather 100. We wrapped this up as version 0.9.850.1.0, having prepared a full (github-only) tarball and the release candidate 9.850.rc1 a few days ago. Both the release candidate and the release got the full reverse depends treatment, and no issues were found.

Changes in the new release below.

Changes in RcppArmadillo version 0.9.850.1.0 (2020-02-09)

  • Upgraded to Armadillo release 9.850.1 (Pyrocumulus Wrath)

    • faster handling of compound expressions by diagmat()

    • expanded .save() and .load() to handle CSV files with headers via csv_name(filename,header) specification

    • added log_normpdf()

    • added .is_zero()

    • added quantile()

  • The sparse matrix test using scipy, if available, is now simplified thanks to recently added reticulate conversions.

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.
