Earlier today, Conrad Sanderson released another bug-fix version 3.0.2 for the still fairly recent 3.0.0 version of his excellent Armadillo C++ template library for linear algebra. The new RcppArmadillo release also appeared on CRAN this morning.

Beside Conrad’s bugfix in Armadillo itself, he also convinced us to unroll a change imposed by R: NDEBUG is now being defined unconditionally when compiling R packages. In Armadillo’s case, this suppresses a number of useful things including bounds-checking. So we now undefine this symbol in the initial RcppArmadillo headers. Users can still set it manually, and/or define ARMA_NO_DEBUG.

The short NEWS entry follows below. 2012-04-19

    o   Upgraded to Armadillo release 3.0.2

          * fixes for handling diagonal matrices

    o   Undefine NDEBUG if it has been set (as R does) as this prevents a
        number of useful debugging checks. Users can still define it or
        define ARMA_NO_DEBUG if they want a 'non-development' build

Courtesy of CRANberries, there is also a diffstat report for relative to 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.
