snippets_read(language = "r", path = snippets_path(language))
language of the snippet. Choices are "r", "c_cpp", "html",

path to .snippets file
A named list of snippets, each of which is a single string that includes tabs at the start of each line.
Note that a .snippets file for a language may not yet exist. If it does not exist, go to Preferences->Code->Edit Snippets in RStudio, make a trivial change to the language of choice (for example, a new empty line), and click Save. This will create the language file in ~/.R/snippets/<language>.snippets with defaults included.
