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
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
