Syntax highlight
From OPOSSEM
Syntax_highlighting is a useful way to display a programming language or code on a wiki page. The OPOSSEM wiki uses a syntax highlighting extension to facilitate the highlighting of programming languages or scripts. A partial list of supported languages can be found on the extension support page.
In addition to the above list, R code can be highlighted by using the syntax <syntaxhighlight lang=rsplus> </syntaxhighlight>
