+--  - Nvim-R will detect *.R, *.Rmd, *.qmd files on its own
+--    These are 3 distinct file types
+--    REF:  https://github.com/jalvesaq/Nvim-R/issues/724
+--  - "The pattern to recognize chunks of R code in Rmd files is hardcoded in Nvim-R/ftplugin/rmd_nvimr.vim, Nvim-R/R/start_r.vim, R-Vim-runtime/syntax/rmd.vim, and R-Vim-runtime/indent/rmd.vim"
