The R Users Group meets roughly ever month on the top floor of the Public Health Building (Normally N512 in Public Health).
We're also on Meetup, through TechCorridor (One of our meetups is: https://www.meetup.com/techcorridorio/events/241813824/)
Our Slack channel is #data, on the TechCorridor server
We have an emailable Active Directory group setup for this meeting. We use this over a listserv for data set, and repository access. We also have a repository on the Github Enterprise server.
