You don't need to use command line tools -- I showed how to do it by 
creating an R Markdown document with each page of the PDF on a numbered 
page of the result.

Here's a minor improvement of my post:

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

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

    \addtocounter{page}{-1}

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


This works regardless of the number of pages in Rplots.pdf.
