How to convert R reveal.js presentation to pdf?

Question

I made a presentation in R, using one of the reveal.js templates (using revealjs R package).

By default, its generating a html file and when opened for presentation it displays top part of the browser including bookmarks, filepath etc... I can turn off bookmarks bar but not the filepath part, I need to present this in a formal setting so exporting the presentation to pdf seems like a better option.

Does anyone know how to export it to pdf? Can I add anything in the YAML header so that the output will be pdf and not html?

Below is the sample code, it generates "test.html" file. I want to generate "test.pdf" while preserving all other properties of presentations e.g transitions, interactive plots etc...

---
title: "test"
output: revealjs::revealjs_presentation

If a manual solution is OK for you (no automatic generation of PDFs when you knit):

Open your HTML file in the browser and add ?print-pdf to the URL, e. g.

http://index.html?print-pdf

You can then print the slides into PDF (e. g. with Ubuntu Linux + Firefox + "save to file" printing option).
