Conrad released a first bug-fix release 3.800.1 of Armadillo earlier today. This has been wrapped up in release 0.3.800.1 of RcppArmadillo as usual. This release also contains a very nice function sample() (contributed by Christian Gunning) which provides sampling (with or without replacement) at the C++ level modeled after what we are used to in R itself. We also refactored the unit tests into just two compilation units to speed testing up a little.

The summary of the main changes follows:

Changes in RcppArmadillo version 0.3.800.1 (2013-03-12)

  • Upgraded to Armadillo release Version 3.800.1 (Miami Beach)

    • workaround for a bug in ATLAS 3.8 on 64 bit systems

    • faster matrix-vector multiply for small matrices

  • Added new sample() function and tests contributed by Christian Gunning

  • Refactored unit testing code for faster unit test performance

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.
