Choose the pdfengine for RMarkdown Report

[MYheavyGo]

I want to know if it this possible to add a  new input and use a different pdfengine (like wkhtmltopdf) and not the default "pdflatex".

Or change it with the metadata (yaml).

Thank you

Not sure about what you want to do, because `wkhtmltopdf` is a translator from html to pdf.

Rmarkdown use `pandoc` to generate document. Anyway, you can change latex engine, if you need, but with some restrictions, you can use one of “pdflatex”, “lualatex”, “xelatex”, “tectonic”.

output:
    pdf_document:
        latex_engine: lualatex

You can find many configuration options in External link to document configuration 

Hope this helps
