RcppArmadillo 0.12.8.1.0 on CRAN: Upstream Fix, Interface Polish
Armadillo is a powerful and expressive C++ template library for linear algebra and scientific computing. It aims towards a good balance between speed and ease of use, has a syntax deliberately close to Matlab, and is useful for algorithm development directly in C++, or quick conversion of research code into production environments. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 1130 other packages on CRAN, downloaded 32.8 million times (per the partial logs from the cloud mirrors of CRAN), and the CSDA paper (preprint / vignette) by Conrad and myself has been cited 578 times according to Google Scholar.
This release brings a new upstream bugfix release Armadillo 12.8.1 prepared by Conrad yesterday. It was delayed for a few hours as CRAN noticed an error in one package which we all concluded was spurious as it could be reproduced outside of the one run there. Following from the previous release, we also use the slighty faster ‘Lighter’ header in the examples. And once it got to CRAN I also updated the Debian package.
The set of changes since the last CRAN release follows.

Courtesy of my CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the Rcpp R-Forge page.
