RcppArmadillo 0.2.14 and 0.2.15

March 4, 2011

(This article was first published on Thinking inside the box , and kindly contributed to R-bloggers)

A few days ago Conrad Sanderson released version 1.1.6 of his Armadillo templated C++ library for
linear algebra. Accordingly, I made a new release 0.2.14 of RcppArmadillo,
our Rcpp-based
integration into R which included a
few local fixes. However, while I updated SVN at the
R-Forge project I
didn’t update the final tarball so Armadillo 1.1.6 wasn’t in it. That is corrected in
the 0.2.15 upload which is now on CRAN and its mirrors.

The short NEWS file extract for both releases follows, also containing
Conrad’s entry for 1.1.6. A few minor tweaks were added but no user-visible

0.2.15  2011-03-04

    o   Upgraded to Armadillo Version 1.1.6   “Baby Carpet Shark”

         * fixed size matrices and vectors can use auxiliary (external) memory
         * .in_range() can use span() arguments
         * subfields can use span() arguments

0.2.14  2011-03-02

    o   Support Run-Time Type Information (RTTI) on matrices by setting the
        state variable vec_state in Row and Col instantiation, with thanks to
        Conrad Sanderson for the hint

    o   fastLm code simplified further by instantiating the Armadillo matrix
        and vector directly from the SEXP coming from R

    o   inst/doc/Makefile now respects $R_HOME environment variable

And courtesy of
CRANberries, here are
the diffs
