Open a *.Rmd or *.rmd file to work with R Markdown. Depending on the configuration in the preamble, you either produce an HTML or PDF output. Do not forget to switch the panel for the rendered output accordingly. Here is an example of R markdown producing a pdf file:

If you produce PDF and HTML output, you can see both after splitting the panel.

There is a brief tutorial on R Markdown in the Project Library. To view the sample files, do the following:

Open a project where you want the copied files to be placed.
Open the Files tab.
Click “Library” at upper right.
