Add pdf file in Rmarkdown file

Question

Is it possible to display a pdf file in an Rmarkdown file? Say, for example, a previously saved image :'myimage.pdf'

What I am aiming is a form of "\includegraphics[width=0.5]{myimage.pdf}"

Answer 1

You can insert this directly into your R Markdown. The alternate name will only be displayed if the image does not load.

![Alternate Name](file.pdf){width=500px}

Answer 2

An update from the very end of 2017
It is possible to import a PDF image using knitr::include_graphics(), e.g.

{r label, out.width = "85%", fig.cap = "caption"} include_graphics("path-to-your-image.pdf")
