Question

I have a very long R script files (one has 2723 lines), can I create a Table of Contents or Index to navigate through a file?

I would like to create a table of contents that points to a specific line on my text, say I have 20 variables to analyze, a table of contents would have 20 items.

You can insert sections using CTRL+SHIFT+R (Cmd+Shift+R on the Mac)

Maybe u can click the button on the right top corner, Next to the source button. Unfortunately, I can't post the pic here.

Or if you want to export to PDF, HTML, or even a word file of your codes with its results, you can try Rmarkdown to make a TOC instead of a script.
