I was looking for a way to change heading format in RMarkdown (pdf) and found this code which works just fine.
---
output: pdf_document
header-includes:
- \usepackage[tiny]{titlesec}
\titleformat*{\section}{\center\bfseries}{}
---
However, the heading are not correct in the bookmarks of the document, i.e., all sections ends up a level lower than the previous (regardless of their actual level).
Here is an example.
---
output: pdf_document
header-includes:
- \usepackage[tiny]{titlesec}
\titleformat*{\section}{\center\bfseries}{}
---
# Level 1
# Level 1
## Level 2
### Level 3
# Level 1
## Level 2
And this is the resulting bookmarks.
Thank you,
