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!

🔗 Open Call for rOpenSci Champions Program Applications!

We are pleased to open the call for the second cohort of Champions and Mentors for the rOpenSci Champions Program 🎉 !

This 12-month-long program will continue to support our goal of identifying, recognizing, and rewarding passionate community members who help the community grow and improve. The activities include cohort-based training, project development, and personal mentorship.

This program focuses on people who belong to groups that are historically and systematically excluded from the open software and research software communities and who are interested in contributing to rOpenSci and the broader open source and research software communities.

You can apply to be a champion or a mentor until September 4th.

More information on eligibility, timeline, curriculum, application process, etc. is on the program webpage.

🔗 Community call: Mentoring & Training Program for Scientific Open Source Champions

Tuesday, 25 July 2023 14:00 UTC. More info.

Champions programs are designed to identify, recognize, and reward emerging leaders within a community. The rOpenSci Champions Program is part of a series of activities and projects we are carrying out to ensure our research software serves everyone in our communities, which means that it needs to be sustainable and open, and built by and for all groups.

On this call Beatriz Milz, Victor Ordu and Carolina Pradier will share their experience of being rOpenSci mentors and champions. We will highlight the benefits of being part of the program for you and for your community, what kind of learning, activities and opportunities an open source community champions program provides. rOpenSci Community Manager Yani will present the details of our Champion Program and answer all your questions about it.

🔗 Call for maintainers

🔗 Call for comaintainers

Refer to our somewhat recent blog post to identify other packages where help is especially wished for! See also our help wanted page – before opening a PR, we recommend asking in the issue whether help is still needed.

🔗 Package development corner

Some useful tips for R package developers. 👀

🔗 Check for partial matching as part of your testing & CI process

You can change your options to generate warnings on partial matching:

  warnPartialMatchAttr = TRUE,
  warnPartialMatchDollar = TRUE,
  warnPartialMatchArgs = TRUE 

But your options and Rprofile are ignored by R CMD check.

A way to still get warnings in your continuous integration is to integrate it to testthat by creating a special setup-options.R file, as in This file could also be used to change any other options (but use with caution to not create situations where it’s too difficult to debug).

Thanks to Hugo Gruson for this tip!

🔗 Change in R-devel for comparing versions

Does your package compare version with code snippets like some_version >= 1.5? If so, you might encounter the warning below with R-devel.

  Warning in `.make_numeric_version()`:
  invalid non-character version specification 'x' (type: double)

Reference, toot.

To avoid it, you need to make your comparison a character vector: some_version >= '1.5'

Example commit fixing this, in usethis.
