I recently came across the good talk by the always good Yiuhi Xie at the Rstudio conference about Pagedown. You can see it by yourself reaching out the rstudio website or clicking the image below:
Pagedown is a newly released package ( still in experimentary status) with a really promising mission: help you build beautiful PDFs documents from our beloved Rmarkdown. More precisely it takes Rmarkdown files and render them into html files already “paged” and ready to be saved/converted into PDF.
