R package creation made easy: Functions!

Do you want to learn how to develop R packages from scratch? This R-Ladies Cologne series is just for you! Together, we’ll walk through every step of package development, from writing your first function to submitting your package to CRAN.

To launch this series, our guest Sébastien Rochette introduced his package {fusen}, which turns R Markdown files into fully functional R packages. You can watch the first workshop here: https://youtu.be/wAkZvwPK1P4?si=w_dYxTwhLKRxGtzz

In this second meeting, the R-Ladies Cologne team is organizing a hands-on workshop on functions - the building blocks of packages!

We will teach you:

• How do functions work?
• What are dependencies, and how to address them?
• How to document your functions with Roxygen?

You will then collaborate in teams to build functions for a real package that will be submitted to CRAN in the final meeting of this series. It does not matter if you are a beginner or experienced R user, this workshop series welcomes all!

When?
📅 Date: 29.08.2025
🕒 Time: 3:00pm CEST

We can’t wait to see many of you there! Let’s build packages together. 💪👩‍💻
