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:
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.
