The OCRUG Hackathon, hosted by the Orange County R Users Group and the UCI Paul Merage School of Business is a two day event where we will "hack" a data set for fun, education, and prizes. The focus of the event is on education and teamwork, with the main goal of taking a data set from its "raw" form all the way through to a final "product" (e.g. visualization, insight, presentation). At the end of the event, teams will present their work in short presentations. Fellow attendees will help judge the work with prizes awarded in several categories (more below).
The event will start with a series of practical educational tutorials to get you started with fundamental data analysis using the R programming language, followed by working sessions where teams will explore and analyze a data set in preparation for the team presentations. Participants will work in small teams, ~ 5 people each.
This event is open to data scientists, enthusiasts and hackers of all levels, from the beginner to the highly experienced. If you are a beginner, it may be helpful to do some preparatory learning before the event — see the suggested resources below. If you are an experienced user, we look forward to you sharing your expertise with others. Assisting others, even across teams, is highly encouraged.
- The hackathon is primarily an educational event, not a competition. We hope that the event will allow participants to practice their skills, as well as teach and learn from others.
- Novice Users: provide an opportunity to work with a real-world data sets from start (acquire the data) to finish (produce a final presentation on the findings from their work).
- Experienced Users: provide an opportunity to practice data analysis skills in a structured environment, interact with others, and assist new users.

- All participants will work on teams, with approximated 5 people each.
- Participants will be randomly assigned into teams during the Introduction session.
- Teams and individuals are free to work when and how they'd like. However, we recommend using the provided Zoom break-out rooms throughout the event so teams can work together more easily.
- Teams will select a team name to use throughout the hackathon.
- Assisting others within and between teams is highly encouraged.
See the presentation guidelines for the presentation requirements. Awards and prizes will be determined by fellow hackathon participants.
Below is a list of the awards and prizes:
- Best Insight (Amazon Gift Card)
- Best Visualization (Amazon Gift Card)
- Best Presentation (Amazon Gift Card)

Overview slides on the event can be found here (PDF)
Two short tutorials will be given on Saturday morning covering essential data analysis topics using R. The tutorials as aimed at R users who have already have some familiarity with the language, but could also be a useful reference for R beginners or users of other programming languages.
- Tutorial 1: Introduction to Tidy Data & Data Manipulation with the tidyverse Slides
- Tutorial 2: Introduction to Data Visualization with ggplot2 Slides
On Saturday evening, we will have an hour long data challenge event, to take a break from the main hackathon work. This will be an opportunity to interact with other participants outside of your team, practice your data hacking skills on a new data set, and win prizes.
