Earlier this week, Conrad released Armadillo 7.600.1. The corresponding RcppArmadillo release 0.7.600.1.0 is now on CRAN and in Debian. This follows several of rounds testing at our end with a full reverse-dependency of a pre-release version followed by another full reverse-depency check. Which was of course followed by CRAN testing for two more days.

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) 298 other packages on CRAN — an increase of 24 just since the last CRAN release of 0.7.500.0.0 in October!

Changes in this release relative to the previous CRAN release 0.7.500.0.0 are as follows:

Changes in RcppArmadillo version 0.7.600.1.0 (2016-12-16)

  • Upgraded to Armadillo release 7.600.1 (Coup d’Etat Deluxe)

    • more accurate eigs_sym() and eigs_gen()

    • expanded floor(), ceil(), round(), trunc(), sign() to handle sparse matrices

    • added arg(), atan2(), hypot()

Changes in RcppArmadillo version 0.7.500.1.0 (2016-11-11)

  • Upgraded to Armadillo release 7.500.1

  • Small improvement to return value treatment

  • The sample.h extension was updated to the newer Armadillo interface. (Closes #111)

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.
