RcppArmadillo 0.2.8

Version 0.2.8 of RcppArmadillo is now on CRAN. This updates the included Armadillo template library to version 0.9.90 which Conrad released two few days ago. RcppArmadillo makes it easy to write highly efficient and highly readable C++ code for linear algebra (based on Armadillo) in R extensions (using Rcpp for the interface).

The short NEWS file extract follows, also containing Conrad's entry for 0.9.90::

    o   Upgraded to Armadillo 0.9.90 "Water Dragon":

         * Added unsafe_col()
         * Speedups and bugfixes in lu()
         * Minimisation of pedantic compiler warnings

    o   Switched NEWS and ChangeLog between inst/ and the top-level directory
        so that NEWS (this file) gets installed with the package

More information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
