Add a table of contents

Another cool feature of RMarkdown reports (whether HTML or PDF) is an automatically generated table of contents (TOC). And with several settings, you can customize your TOC quite a bit:

You add a table with toc: true and specify whether it should be floating (= whether it moves along as you scroll) with toc_float.

The depth of your TOC is set with toc_depth.

Change the YAML header so your report now contains a non-floating TOC.
- Use the toc and toc_float YAML keys for this.
- Be sure to specify the correct values (i.e. 'true' or 'false')!
Make your TOC also display the level 4 section header at the end of the report. By default, TOCs go only two levels of sections deep.
- Use the toc_depth setting together with the correct value for this.
