armadillo image

A new RcppArmadillo bugfix release arrived at CRAN today. The version is another minor bugfix release, and based on the new Armadillo bugfix release 9.200.7 from earlier this week. I also just uploaded the Debian version, and Uwe’s systems have already create the CRAN Windows binary.

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) 559 other packages on CRAN.

This release just brings minor upstream bug fixes, see below for details (and we also include the updated entry for the November bugfix release).

  • Upgraded to Armadillo release 9.200.7 (Carpe Noctem)

  • Fixes in 9.200.7 compared to 9.200.5:

    • handling complex compound expressions by trace()

    • handling .rows() and .cols() by the Cube class

  • Upgraded to Armadillo release 9.200.5 (Carpe Noctem)

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.
