Why doesn't the syntax highlighting work?

Question

I tried several ways of how to do syntax highlighting for R in this question, but it doesn't work. I tried ```R (see revision 3 of the question) and  (see revision 2) but neither of them does work, despite the instructions in Syntax highlighting language hints.

PS: note that I don't want to tag the question with the R tag because it is not R specific.

The canonical is What is syntax highlighting and how does it work?. — This_is_NOT_a_forum, Commented Nov 30, 2019 at 2:45
I had similar with powershell,  resolved it — quantme, Commented Oct 30, 2023 at 18:41

I've just submitted a suggested edit using the old-style code blocks and a language hint:

<!-- language: lang-r -->

That seems to work:

Your last version (revision 3) might not work since you used a capital R; language hints need to be in lower case.

Thanks! These are really catches! lang-r instead of just R! And small r instead of R - R is always written with capital R. I think the documentation needs update with list of possibilities and maybe the parser could be more tolerant as well.

It looks like it registers both upper- and lower-case varients. In theory it should work but I guess there's something else in the way.

@Tomas the list of possibilities is in the linked Prettify documentation.
