Just before Xmas, Conrad Sanderson released version 1.1.0 of
Armadillo, his templated C++ library
for linear algebra. Which I only noticed this week, so here comes version 0.2.11 of
RcppArmadillo, our
Rcpp-based
integration into R.

The only other change is the addition of an unexported function
SHLIB which can be used to compiled a single source file into a
loadable shared library file for R, while automagically find Rcpp and
RcppArmadillo headers and the Rcpp library.

The short NEWS file extract follows, also containing Conrad’s entry for 1.1.0:

0.2.11  2011-01-06

    o   Upgraded to Armadillo Version 1.1.0   “Climate Vandal”

         * Extended submatrix views, including access to elements whose
           indices are specified in a separate vector
         * Added handling of raw binary files by save/load functions
         * Added cumsum()
         * Added interpretation of matrices as triangular via
           trimatu()/trimatl() 
         * Faster solve(), inv() via explicit handling of triangular matrices 
         * The stream for logging of errors and warnings can now be changed 

    o   New unexported R function SHLIB, a small wrapper around R CMD SHLIB,
        which can be used as   Rscript -e "RcppArmadillo:::SHLIB('foo.cpp')"

And courtesy of
CRANberries, here is
