Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 779 other packages on CRAN.
This release ties up a few loose ends from the recent 0.10.1.0.0.
Changes in RcppArmadillo version 0.10.1.2.0 (2020-11-15)
Upgraded to Armadillo release 10.1.2 (Orchid Ambush)
Remove three unused int constants (#313)
Include main armadillo header using quotes instead of brackets
Rewrite version number use in old-school mode because gcc 4.8.5
Skipping parts of sparse conversion on Windows as win-builder fails
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 R-Forge page.
A new release 0.0.17 of RcppAnnoy is now on CRAN. RcppAnnoy is the Rcpp-based R integration of the nifty Annoy library by Erik Bernhardsson. Annoy is a small and lightweight C++ template header library for very fast approximate nearest neighbours—originally developed to drive the famous Spotify music discovery algorithm.
This release brings a new upstream version 1.17, released a few weeks ago, which adds multithreaded index building. This changes the API by adding a new ‘threading policy’ parameter requiring code using the main Annoy header to update. For this reason we waited a little for the dust to settle on the BioConductor 3.12 release before bringing the changes to BiocNeighbors via this commit and to uwot via this simple PR. Aaron and James updated their packages accordingly so by the time I uploaded RcppAnnoy it made for very smooth sailing as we all had done our homework with proper conditional builds, and the package had no other issue preventing automated processing at CRAN. Yay. I also added a (somewhat overdue one may argue) header file RcppAnnoy.h regrouping defines and includes which should help going forward.
Detailed changes follow below.
Changes in version 0.0.17 (2020-11-15)
Upgrade to Annoy 1.17, but default to serial use.
Add new header file to regroup includes and defines.
Upgrade CI script to use R with bspm on focal.
