Extract the ids of the rtweet data if present. Depending on the object type it returns either users ids, tweet ids or rules ids.
Examples
if (auth_has_default()) {
users <- lookup_users(c("twitter", "rladiesglobal", "_R_Foundation"))
ids(users)
followers <- get_followers("_R_Foundation")
head(ids(followers))
friends <- get_friends("_R_Foundation")
head(ids(friends))
}
