It is with great sadness that we announce the passing on 1 April of Tomáš Kalibera, a valuable member of the R Core Team for close to 10 years, after a short but aggressive illness.
Tomáš brought in fresh perspective and knowledge, enabling him to improve many aspects of R, including performance and reliability. He created many tools to support package authors, and modernized the Windows build of R.
He is survived by his wife and 1 year old son. A full obituary will be posted in due time.

We are responding to this call for evidence:
https://ec.europa.eu/info/law/better-regulation/have-your-say/initiatives/16213-European-Open-Digital-Ecosystems_en
Do you have concrete examples of the added value of #Rstats in the public or private sectors?
Include the most important factors (risk, lock-in, security, innovation...) to assess the added value.
Thanks!

New #RStats blog entry from Tomas Kalibera: Debugging Sensitivity to C math library and mingw-w64 v12.
C math library functions, such as exp or sin, are not guaranteed to be “precise”. The results might be slightly different on different platforms. This post presents a tool "mdebug" which allows package authors to debug any potential issues with C math functions in their package.

It is with great sadness that we learned of the death John Fox this week. He was the author of numerous books on applied statistics and accompanying #RStats packages including car, effects, Rcmdr, ivreg, and matlib. John was a member of the R Foundation until 2023.
