We are a group of librarians, faculty, researchers, graduate students, undergraduate students, and others affiliated with the University of Pennsylvania who use R. We work on collaborative training projects to grow our combined skills and promote the use of reproducible research and coding practices.

We welcome individuals from all skill levels — including (and especially) people who haven’t used R but want to, and who have never used a scripting language (whether R, Python, etc.) before.


We meet every Wednesday from 11:00am-12:00pm.

When possible, we agree in advance on topics for specific weeks.

Finding Us

Our Meeting Space

We meet in the Weigle Information Commons (WIC) Seminar Room, on the first floor of the Van Pelt-Dietrich Library Center.


There’s no need to tell us in advance that you’re coming in, and no requirement that you attend every week (though we encourage doing so!).

Our Digital Spaces

You can chat with other use-Rs on our Slack channel (you’ll need to create an account with your U. Penn email address).

You can find us on GitHub, as well.
