R markdown: can I insert a pdf to the r markdown file as an image?

Question

I am trying to insert a pdf image into an r markdown file. I know it is possible to insert jpg or png images. I was just wondering if it is also possible to insert a pdf image.

Answer 1

None of the answers outlined worked well for me in terms of sizing the pdf, so adding another answer using the code chunk options for out.height and out.width to control the size:

```{r out.height = "460px", out.width='800px', echo=F}
knitr::include_graphics("./images/imagename.pdf")
```
