using rstudio snippets in rmd extension files


do rstudio snippets work on non r file extensions? i am trying to use snippets in an rmd and the source editor is not responding.

are there definitions i need to add the to .R/snippets/r.snippets file to enable it to work on multiple extensions?


If I change the language in the IDE from R to Rmd in the bottom rhs of the source editor then the snippets react.
