A new minor release 3.910.0 of Armadillo came out a few days ago. A new RcppArmadillo release 0.3.910.0 was provided rightaway, and after a brief back-and-forth with CRAN (mostly having to do with the non-standard vignette corresponding to our CSDA paper and its use of LaTeX minted) is now on CRAN and also in Debian.
Conrad made some standard cross-products faster, and added
all() functions. We also added an extension header for more
automated conversion of sparse matrices (which is
already used by a post on the Rcpp Gallery).
The complete list of changes is below.
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.
