How do I include external graphics in my knitr documents?

Question

I have been using knitr in conjunction with my R work.

I have some external graphics that I would like to include in my knitr HTML document.

I can't seem to find a method to do so. Should I use R Markdown or is there a more knitr-specific manner to do this?

Thanks for the pointers.

Try the notation

!['Gauss'](https://goo.gl/eXN77h)

as in this OpenCPU example app.
