Here are some conferences focused on R taking place in the next few months:
Oct 26: Nor'eastR Conference (Providence, RI). A one-day R conference, organized by grassroots R community members in the Northeastern US.
Nov 8-9: DC R Conference (Washington, DC). From the same organizers as the fantastic New York R Conference, this DC-based outpost will feature speakers including Mara Averick, Roger Peng, and Emily Robinson.
Nov 9: EARL Houston (Houston TX). The EARL roadshow continues with a stop in Texas.
Nov 13: EARL Boston (Boston, MA). The EARL roadshow concludes with a 1-day event in Boston.
Dec 8: SatRDays DC (Washington, DC). Talk proposals for this Washington, DC instance of SatRDays are open until October 31.
Jan 15-18 2019: RStudio::conf (Austin, TX). The annual conference from the makers of RStudio takes place in Austin, Texas.
I go to a lot of conferences these days, but those organized by the R community remain my favorite. Attending one of these events is a great way to learn new R skills, but equally importantly to meet other R users from a different disciplines, and perhaps discover that their problems and applications aren't that dissimilar from your own. I'll be at many of the events listed above, and I look forward to meeting you all there.
If you can't find an event at the right time or place for you, take a look at the index linked below for a list of upcoming meetups, conferences and events from the R community. (Know one that's not listed? You can submit a pull request by clicking the pencil icon in the top row.)
