 Making a contribution to a large open source software project like the R project can seem very daunting. This walkthrough aims to demonstrate how R users can contribute simple fixes to the code or documentation in base R, helping to maintain this fundamental software for data science. We will briefly look at: 1) How to find a good bug to work on, 2) Getting to the the root of the issue, and 3) How to propose a fix.
