Another release (1.1.90) by Conrad Sanderson for his wonderful
Armadillo templated C++ library for
linear algebra appeared yesterday. Consequently, a new
release 0.2.17 of
RcppArmadillo,
our Rcpp-based
integration into R is now on CRAN mirrors.

The short NEWS file extract follows below containing just Conrad’s entry for
1.1.90. No further changes from our side.

0.2.17  2011-03-22

    o   Upgraded to Armadillo Version 1.1.90  "Inside Job"

         * Added .min() & .max(), which can provide the extremum's location
         * More robust mean(), var(), stddev()

And courtesy of
CRANberries, here are
the

diffs to the previous release
.
