An new version 0.0.9 of RcppAnnoy, our Rcpp-based R integration of the nifty Annoy library by Erik, is now on CRAN. Annoy is a small and lightweight C++ template header library for very fast approximate nearest neighbours.

This release corrects an issue for Windows users discovered by GitHub user ‘khoran’ who later also suggested the fix of binary mode. It upgrades to Annoy release 1.9.1 and brings its new Manhattan distance to RcppAnnoy. A number of unit tests were added as well, and we updated some packaging internals such as symbol registration.

And I presume I had a good streak emailing with Uwe’s robots as the package made it onto CRAN rather smoothly within ten minutes of submission:

Changes in this version are summarized here:

Changes in version 0.0.9 (2017-08-31)

  • Synchronized with Annoy upstream version 1.9.1

  • Minor updates in calls and tests as required by annoy 1.9.1

  • New Manhattan distance modules along with unit test code

  • Additional unit tests from upstream test code carried over

  • Binary mode is used for save (as suggested by @khoran in #21)

  • A new file init.c was added with calls to R_registerRoutines() and R_useDynamicSymbols()

  • Symbol registration is enabled in useDynLib

Courtesy of CRANberries, there is also a diffstat report for this release.
