Watermark in rmarkdown

Question

I have researched and found how to create a watermark in an rmarkdown document.

It works great on basic text, but when you have a plot heavy page, it gets hidden beh

Answer 1

Try using

header-includes:
   - \usepackage{eso-pic,graphicx,transparent}

and then on the first page of your document (within the LaTeX part), add

\AddToShipoutPictureFG{
  \AtPageCenter{% or \AtTextCenter
    \makebox[0pt]{\rotatebox[origin=c]{45}{%
      \scalebox{5}{\texttransparent{0.3}{DRAFT}}%
    }}
  }
}

This should add a rotated DRAFT message (semi-transparent) in the ForeGround (over top) of the page.
