#48: r2u Talk Re-Recorded

Welcome to post 48 in the R4 series, and to video 8 in this series.

Last week I had the honour of giving the opening talk at the 11eme Rencontres R at the Université de Mons in Belgium as an invited plenary talk. Big thanks again to Philippe Grosjean and Kathy Huet for the invitation, and for organising a lovely conference.

Being the opening talk, we were still sorting out projector issues when I started so I forgot to set a timer, and consequently ran out of time like a newbie. It occured to me that I could simply re-record the talk in front of my slides just as I do for my STAT 447 students. So I sat down this morning and did this, and the video is now online:

The slides are available as well.

For questions or other feedback, please consider using the r2u GitHub repo issues section.

RcppDate 0.0.6: New Upstream

RcppDate wraps the featureful date library written by Howard Hinnant for use with R. This header-only modern C++ library has been in pretty wide-spread use for a while now, and adds to C++11/C++14/C++17 what will is (with minor modifications) the ‘date’ library in C++20. The RcppDate package adds no extra R or C++ code and can therefore be a zero-cost dependency for any other project; yet a number of other projects decided to re-vendor it resulting in less-efficient duplication. Oh well. C’est la vie.

This release syncs with upstream release 3.0.4 made yesterday which contains a few PRs (including one by us) for the clang++-20 changes some of which we already had in release 0.0.5. We also made a routine update to the continuous integration.

Changes in version 0.0.6 (2025-05-29)

  • Updated to upstream version 3.0.4

Courtesy of my CRANberries, there is also a diffstat report for the most recent release. More information is available at the repository or the package page.
