An R package containing an RStudio Addin to help you insert R Documentation (Rd) markup to your package’s function documentation.

You put a snorkel in your mouth to help you breathe oxygen; you put a {snorkel} in your Addins to help you prepare documentation with {roxygen2}.


Install from Github with:

install.packages("remotes")  # if not already installed


To use the Addin:

  1. Select some text in your function documentation to which you’d like to apply Rd markup (e.g. bold, italics), or place the cursor where you’d like to insert an Rd skeleton (i.e. the functions that insert lists)
  2. Click the ‘RStudio Addins’ dropdown at the top of the RStudio IDE
  3. Scroll/search for ‘SNORKEL’ and click the function you want

For speed, you can also search for the functions from the RStudio command palette or create custom RStudio keyboard shortcuts.

So, for example, you could highlight the word bold in #' This is bold and select the ‘Format Bold’ function from the Addin, resulting in #' This is \strong{bold}.

Special cases are ‘Link To Function (Another Package)’ and ‘Link To Function (Another Package, Show Name)’. Both need as input the package name and the function name that you’re linking to, which you should supply in the form ‘package::function’.


For help with {snorkel} functions, take a look at the reference page on the package website, or in your R console type ? followed by the function name for its documentation.
