Are there any standard syntax highlighting rules for R? If yes, where can they be found?
Or does each editor, IDE, package (e.g., the highlight package) create their own rule set?

Syntax highlighting determines the color and style of source code displayed in the Visual Studio Code editor. It is responsible for colorizing keywords like if or for in JavaScript differently than strings and comments and variable names.
Syntax highlighting is a feature of text editors that are used for programming, scripting, or markup languages, such as HTML. The feature displays text, especially source code, in different colours and fonts according to the category of terms.
Syntax highlighting allows code in posts to be highlighted based on the language it's written in, to make it easier to read.
Each editor creates their own rule set. For historical reasons, each editor has implemented syntax highlighting in its own way. Having a cross-editor standard may be possible using, for example, GeSHi, but it would almost certainly require a lot of effort getting editor makers to sign up to it, especially if they already have their own system.
Eclipse uses .hrc files for storing syntax information.
RStudio has a file called r_highlight.html.
Notepad++ stores keywords for different languages in a file named langs.model.xml.
Textpad has its own .syn format for the code highlighting.
TextWrangler has a plugin.
