Use internal links in RMarkdown HTML output

Question

I am using R Studio to create a markdown document. I tried:

Jump to [Header 1](#anchor)

I would like

Answer 1

Pandoc supports explicit and implicit section references for headers; see the pandoc manual.

• explicit: you give a custom name to a header ## Test {#test} and later refer to it with a link syntax: see [the relevant section](#test).
• implicit: headers where you don't set a custom name, like ## Test, can still be refered to: See the section called [Test].

Both syntax should allow you to click on the link to go to the anchor, and should work in most output format. (only tested with html and pdf).

output:  pdf_document

## A section

blah blah

## A second section with a custom identifier {#custom}

blah blah

## Links

You can use implicit references to refer to sections
you have not explicitly named, like this: 
see [A section]. 

You can use links to refere to sections with explicit
references, like this: see [the second section](#custom).
