Extract specific code chunks from a QMD/RMD file into a plain R script file

[Erwin_Lares]

Hi code fam,

I am wondering if any of you have suggestions on how to solve this problem.

I have this project I'm working on where I document a workflow from end to end. I start with data ingestion and end up producing some research artifacts like reports and models. The Quarto file has a lot of explaining where I solve the same problem in different ways.

What I would like to do is at the end grab specific code chunks from the Quarto file and turn them into a plain R script file. Can you think of a way to accomplish this?

I'd appreciate whatever suggestion you can send my way,

Erwin

Hi @Erwin_Lares ,

tested Extract code with Quarto – Tutorial: Hello, Quarto hello.qmd. knitr::purl("hello.qmd") returns a hello.R file
