How to find R-lang heavy jobs?

How do I find jobs that use the R language? It's impossible to search the letter "R" on linkedIn or Indeed without getting a bunch of unrelated job postings

"R" is the only programming language I know (stats major) and I can't find a job that uses R because job search engines don't allow you to sort by skill

"R language" is the closest substitute on linkedin but the results are still a jumbled mess of jobs, some looking moreso for other skills (SQL/Python) and mention R passively

I know R-heavy jobs exist but finding them on LinkedIn is virtually impossible
