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.
