Rubber Duck Debugging
The power of talking through your code problems 🦆 💬
It doesn’t have to be a duck
Walk through as if the “duck” has no context
Planning with Pseudo Code
Use plain language before you code (sometimes this means starting by the end)
Get to know your subject qualitatively
Refine your analysis questions
Break it down!
Split your code into multiple R scripts by themes and outputs
Save functions in separate R scripts
Bring to your Quarto document only what you need

How to Ask Good (Code) Questions
How to Ask Good (Code) Questions
The most important part of asking good questions about code is to provide reproducible examples.
A reproducible example contains all necessary code to reproduce your error or to customise your chart.
The reprex package is designed to help guarantee your examples are reproducible.
Examples are Minimal
In addition to making your code reproducible you should try to make it minimal.
Use the smallest, simplest, most built-in data possible.
Think: iris or mtcars. Bore me.
Make your question as focused as possible
Example of a Good Reprex
How can I reorder bars on the y axis?
Using the reprex Package
Select the code that makes your reprex
Open the Addins menu and select “Render reprex…”
Choose the options for where you’re asking your question
Copy and paste the output in the Viewer tab into your question
