Today I gave a short talk about writing R packages at the Research Bazaar 2018 (University of Melbourne). I’ve made my slides available online.
The talk is aimed at R beginners. I assume you already know how to write basic functions and want to take the next step and learn to put these together into packages.
If you are a more advanced R user, I recommend starting with my much longer talk about R packages that I presented at the Melbourne R user group in 2016.
