Ask the main part of your question in the title. This should be concise but informative.
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

[R] How do I create tables with sub columns? (lemmy.blahaj.zone)

submitted 6 months ago by rockSlayer@lemmy.blahaj.zone to c/learn_programming@programming.dev

I need to create a table with summary statistics on a data frame, and I want to group 4 similar columns (N_cases, percent) into 2 broader columns (incident, prevalent), so it would look like this:

| Prevalent | Incident |
|    N | %  |   N | %  |
