Question
Answer and Explanation
To create a table of contents (TOC) in R Markdown without numbers, you can achieve this by utilizing specific YAML configurations and potentially some customization of CSS, although CSS is not required to just remove the numbering itself.
Here is a breakdown of the steps:
1. YAML Front Matter Configuration
- The primary method to control TOC behavior lies in the YAML front matter at the top of your R Markdown document. The toc, toc_depth, and number_sections directives will assist.
2. Removing the Numbers
- To eliminate the numerical prefixes, set the number_sections parameter to false in your YAML header. This step will result in an unnumbered list of headings.
Example YAML Configuration:
---
title: "My R Markdown Document"
output:
html_document:
toc: true
toc_depth: 3
number_sections: false
---
In this snippet:
- toc: true indicates the inclusion of a Table of Contents.
- toc_depth: 3 includes headings up to three levels (e.g., # Heading, ## Subheading, and ### Sub-subheading).
-number_sections: false removes numbers before section titles.
3. How to integrate: Simply add this block of text with correct intendation on top of your document before you start writing your content. Once the document is compiled by your IDE(RStudio etc) you should see an unnumbered table of content on the generated page.
By setting the mentioned number_sections: false your rendered markdown document should not include any numerical index beside the titles inside the Table Of Contents block.
This straightforward setup with R Markdown's YAML header allows you to effectively generate a TOC without any numeric indices, producing cleaner and more suitable results where that specific formatting is required.
