I agree with that comment.  However, if one is stuck with a multipage 
PDF file, and wants to add page numbering, you could use the LaTeX 
pdfpages package.

For example, this R Markdown document includes all 10 plots from 
Rplots.pdf on pages with "x of y" page numbering.

   ---
   title: "Numbered"
   output:
     pdf_document:
       extra_dependencies: ["pdfpages", "fancyhdr", "lastpage"]
   ---

   \cfoot{Page \thepage\ of \pageref{LastPage}}

   \addtocounter{page}{-1}

   \includepdf[pages={1-10},pagecommand={\thispagestyle{fancy}}]{Rplots.pdf}


It would make more sense to do this in a LaTeX document, but I'm not 
sure if Dennis knows LaTeX...
