It remains in limbo at CRAN for no apparent reason. No change appears to be imminent either as the CRAN maintainers continue to play a passive-aggressive game of no communication for any reason. Which is a genuine shame as e [E]verbody involved in the package, i.e. Erik (upstream) and myself but also Aaron (downstream) worked pretty hard and well last weekend (while I was traveling / attending the wonderful celebRtion 2020 conference for the 20th anniversary of the R 1.0.0) to iron out all remaining issues. Installation is pretty flawless and silent as all compiler warnings have been takeb care of even under
-pedantic on a recent version, and the last remaining UBSAN issue is also fixed.
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.
As I wrote in the announcement for 0.0.15 which fixed many-but-not-all issues:
The other important issue is that there will be another 0.0.16 release real soon to incorporate three more small upstream PRs driven by these discussions which kept going on post-release while I was conferencing (or traveling), and which should fix things for good, or so we hope. This should go out probably by the end of the week to not exceed a weekly upload cadence; if you want to see more, or get earlier access, see the git repo which is in fine shape. If you want to see a pre-release on the ghrr drat drop me a line.
As CRAN is holding the package hostage, all I can do now is to release to the Github-hosted R Repository (ghrr) from where you can install it via a simple The package is now on CRAN.
install.packages("RcppAnnoy", repos="https://ghrr.github.io/drat") (or any of the other drat supported commands, see the ghrr page for more). Or wait and wait and wait … until CRAN graces us with a manual admission (given that the previous upload left one small UBSAN issue to fix). One day. Hopefully.
Detailed changes follow below.
