Another Armadillo 7.* release — now at 7.400. We skipped the 7.300.* serie release as it came too soon after our most recent CRAN release. Releasing RcppArmadillo 0.7.400.2.0 now keeps us at the (roughly monthly) cadence which works as a good compromise between getting updates out at Conrad‘s sometimes frantic pace, while keeping CRAN (and Debian) uploads to about once per month.

So we may continue the pattern of helping Conrad with thorough regression tests by building against all (by now 253 (!!)) CRAN dependencies, but keeping release at the GitHub repo and only uploading to CRAN at most once a month.

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.

The new upstream release adds new more helper functions. Detailed changes in this release relative to the previous CRAN release are as follows:

Changes in RcppArmadillo version 0.7.400.2.0 (2016-08-24)

  • Upgraded to Armadillo release 7.400.2 (Feral Winter Deluxe)

    • added expmat_sym(), logmat_sympd(), sqrtmat_sympd()

    • added .replace()

Changes in RcppArmadillo version 0.7.300.1.0 (2016-07-30)

  • Upgraded to Armadillo release 7.300.1

    • added index_min() and index_max() standalone functions

    • expanded .subvec() to accept size() arguments

    • more robust handling of non-square matrices by lu()

Courtesy of CRANberries, there is a diffstat report. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
