required The numerical id of the list.

required You can identify a list by its slug instead of its numerical id. If you decide to do so, note that you'll also have to specify the list owner using the owner_id or owner_user parameters.

optional The screen name or user ID of the user who owns the list being requested by a slug.

optional Specifies the number of results to return per page (see cursor below). The default is 20, with a maximum of 5,000.

semi-optional Causes the collection of list members to be broken into "pages" of consistent sizes (specified by the count parameter). If no cursor is provided, a value of -1 will be assumed, which is the first "page." The response from the API will include a previous_cursor and next_cursor to allow paging back and forth. See Using cursors to navigate collections for more information.

Logical indicating whether to convert the response object into an R list. Defaults to TRUE.

Every user should have their own Oauth (Twitter API) token. By default token = NULL this function looks for the path to a saved Twitter token via environment variables (which is what 'create_token()' sets up by default during initial token creation). For instruction on how to create a Twitter token see the tokens vignette, i.e., 'vignettes("auth", "rtweet")' or see ?tokens.
