And yet another updated of Armadillo by Conrad bringing us to 6.400.2. I folded that yesterday into RcppArmadillo 0.6.400.2.2; and this is now on CRAN and Debian. There was even an interim-CRAN-only release 0.6.300.2.2 with a refinement for tests of imcompleye LAPACK libraries—which we encounter whenver R is build with its own (partial) copy of LAPACK as on Windows, and on bigger computers whenver this was chosen over the default of system LAPACK.

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.

This release brings the following changes:

Changes in RcppArmadillo version 0.6.400.2.0 (2015-12-15)

  • Upgraded to Armadillo 6.400.2 ("Flying Spaghetti Monster Deluxe")

    • expanded each_col(), each_row() and each_slice() to handle C++11 lambda functions

    • added ind2sub() and sub2ind()

    • fixes for corner cases in gmm_diag class

Changes in RcppArmadillo version 0.6.300.2.2 (2015-12-12)

  • Upgraded to Armadillo 6.300.3-test ("Flying Spaghetti Monster")

    • Additional test in auxlib_meat.hpp for limited LAPACK

  • Updated test and #define for limited LAPACK version R might be built with on Unix-alike systems

Courtesy of CRANberries, there is also a diffstat report for the most recent CRAN release. As always, more detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
