Dear rOpenSci friends, it’s time for our monthly news roundup! You can read this post on our blog. Now let’s dive into the activity at and around rOpenSci!
The rOpenSci team is deeply saddened at the loss of Tomáš Kalibera, a member of R-Core and contributor to the R community for almost 10 years. Tomáš passed away on April 1. Our thoughts are with Tomáš’s friends and family at this time.
Read Jan Vitek’s remembrance of Tomáš.
We’re excited to welcome Alec Robitaille and Lucy D’Agostino McGowan as new editors. Alec joins our general review team, and Lucy our statistical software review team. Read more in the post introducing them!
We’re excited to share that we’ve finished selecting the new cohort for the rOpenSci Champions Program! This was not an easy process. The quality of the proposals was exceptionally high, which made the selection both challenging and inspiring. We’re grateful to everyone who applied and shared their ideas with us. Please join us in welcoming our new Champions: Bastián Olea Herrera, Durga Valentina Linares Herrera, José Daniel Conejeros, Denisse Fierro Arcos, Evelia Lorena Coss Navarrete, Gladys Choque Ulloa, Linda Jazmín Cabrera Orellana, Patricia Andrea Loto, Marina Cecilia Cock, María Florencia Tames, and Estefanía Torrejón.
Over the coming months, they will contribute to the R Community through developing new packages, reviewing packages, and submitting packages for peer review. We’re looking forward to working with this amazing group and supporting their projects!
Bioconductor is collaborating with R-universe to gradually modernize parts of its infrastructure, while accommodating the project’s scale, governance, and established processes. In turn, Bioconductor is helping R-universe expand and refine its features as we learn to serve the complex needs of the Bioconductor community. Read more in the blog post.
Yani will deliver her keynote talk “Software Sustainability and Community Management” on Thursday May 7th, 11:15AM–12:15PM ET.
Jeroen will take part in an online discussion panel on Wednesday 20 May at 5:00 PM - 6:00 PM (AEST). The panel is organized by the Statistical Computing and Visualisation section of the Statistical Society of Australia (details).
We have long recommended the goodpractice package, which identifies issues with R packages, and advises how to fix them. Thanks to a huge amount of work by valued community member Athanasia Mo Mowinckel, goodpractice has been extended and improved to include entirely new suites of checks, and improved ability to control which checks are run. A blog post describing the updates will be published soon, but in the meantime, we encourage you to install the current development version and try it out yourself.
Following our blog post about tree-sitter, Tyler Morgan Wall was inspired to create a static analysis tool for targets pipelines (as a VS Code extension).
Read all about coworking!
And remember, you can always cowork independently on work related to R, work on packages that tend to be neglected, or work on what ever you need to get done!
We are exploring hosting a new event, Editors’ Office Hours, where you can drop in to ask questions about rOpenSci Software Peer Review on or near the third Tuesday of each month, alternating among timezones to accommodate different parts of the world.
Upcoming office hours:
useR! 2026 is offering diversity scholarships to support participation from people in underrepresented or historically marginalized groups within the R community. The program includes both registration fee waivers and full needs-based scholarships, which cover conference registration as well as travel and lodging (via reimbursement). Applications are open to eligible participants worldwide until May 10, and will be reviewed based on need, eligibility, and potential impact by a committee from Forwards, RLadies+ Global, and rOpenSci.
Found all the details and important links on the conference website: https://user2026.r-project.org/additional/diversity_scholarship.html

Some useful information for R package developers. 👀
The Jarl CLI by Étienne Bacher received several useful new features for package developers:
They are a nice complement to unreachable_code.
Read more in the release announcement.
Ally Piechowski wrote an insightful post entitled “The Git Commands I Run Before Reading Any Code”, which suggests Git commands which are useful for understanding the code base. For instance a command to determine which files recently changed the most!
To complement this post, Garrick Aden-Buie wrote “a little git-recon bash script that runs them in series, complete with some ascii bar plots”.
Last month we listed several ways to browse the R mailing lists. Newsletter reader Florian Kohrt kindly wrote to us to mention the plain text backup maintained by Michael Chirico.
Andrew Heiss published an useful and interesting deep dive into random seeds.
Are you enjoying the coalesce operator %||% introduced in R 4.4.0?
L %||% Rnewly in base is an expressive idiom for the phrasesif(!is.null(L)) L else R or if(is.null(L)) R else L.
Consider enforcing it via Jarl or lintr.
As a reminder, the operator can be used in older versions of R through the backports R package or by importing it from rlang.
