Coerces user identifier(s) to be evaluated as a screen name(s).





A vector consisting of one or more Twitter user identifiers (i.e., screen names or user IDs).


A vector of class screen_name or class user_id


Default rtweet function behaviors will treat "1234" as a user ID, but the inverse (i.e., treating "2973406683" as a screen name) should rarely be an issue. However, in those cases, users may need to mix both screen names and user IDs. To do so, make sure to combine them as a list (and not a character vector, which will override conflicting user identifier classes). See examples code for example of mixing user IDs with screen names. Note: this only works with certain functions, e.g., get_friends, get_followers.
