A new minor release of RcppArmadillo
is now on CRAN and in Debian.
brings the Armadillo templated C++
library for linear algebra to R by means of Rcpp.

This release contains both a few minor bugfixes from the 4.000 branch of
Armadillo and some enhancements in
RcppArmadillo itself
that are related to the
recent Rcpp 0.11.0 release.

Changes in RcppArmadillo version (2014-02-19)

  • Upgraded to Armadillo release Version 4.000.4

    • fix for randi() generating out-of-interval values

    • fix for saving field objects

    • workaround for a bug in the Intel compiler

  • Updated for Rcpp (>= 0.11.0) by removing linking step
    from build process, added appropriate dependency on Rcpp

  • Updated RcppArmadillo.package.skeleton function accordingly to use proper NAMESPACE import

  • Rewritten rcpparma_hello_world (which is used by the RcppArmadillo.package.skeleton function) to use Rcpp Attributes, and added more examples

  • Added two functions to set Armadillo’s RNGs (ie the system RNG) from a given value and to randomize it, as suggested by Gábor
    Csárdi. Note that these do not work within RStudio (which itself also uses the same system RNG).

Courtesy of CRANberries, there
is also a diffstat report for the
most recent release
As always, more detailed information is on the RcppArmadillo page.
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page.
