RcppArmadillo released and on CRAN

April 19, 2012

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
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
