Social media is one of the ways we do that, so we thought Maintainer Month would be a great opportunity to highlight the people behind the packages through a social media campaign.To run this campaign, we first needed permission from our maintainers to feature them. In our annual maintainer survey, we asked whether they would be interested in being featured in a public spotlight, and many said yes.We also reached out to current and past Champions from our Champions Program, which trains and supports R developers from historically underrepresented groups in the open science community.The result was a month-long series of spotlights: one maintainer at a time, each card sharing who they are, where they come from, and what they maintain.This campaign brought together 37 maintainers from 15 countries, maintaining more than 50 packages that together serve thousands of researchers and data practitioners around the world.The diversity of this group reflects the diversity of the rOpenSci community: archaeologists, bioinformaticians, ecologists, economists, statisticians, sociologists, professors, PhD students, engineers and educators.We created 39 posts on our accounts on LinkedIn and Mastodon, which is bridge to BlueSky. All the posts were shared by other people and organizations and received comments from grateful users.Meet all 37 maintainersHere is the full list of maintainers we celebrated in May.Alex Koiter maintains {mbquartR}, for working with Manitoba’s quarter-section land survey system in watershed and land management research.Andrea Gomez Vargas maintains {ARcenso}, for accessing and analyzing Argentina’s national census data in R.

It takes time that could be spent elsewhere, and it often goes unacknowledged.Every bug fix, every answered issue, every new feature and update is a small gift to the people who depend on that package.We are grateful to all the rOpenSci maintainers.If you use any of these packages, consider saying thank you.You can also let us know how you use these packages by sharing your use case, that we will feature in our website.Want to learn more?
