Formatting R code in WordPress

To show formatted code within a paragraph, for example a function name, use <code>plot</code> which will appear as plot.

To show a block of code, use something like this but using square brackets [] rather than braces {}.

{code language=”r”}
#don't forget comments

Setting the language to R lets the WordPress plugin use appropriate syntax highlighting.

When formatted, the code will look like this

#don't forget comments

There are more options to set line numbers and highlighting by adding extra parameters.


  • Keep the lines of code short – long lines will force the user to scroll.
  • Use the text editor not the visual editor (which may garble your code)
  • Check the code works (it is very tempting to edit it and break it)
