get_collections() and lookup_collections() have been deprecated
since the underlying Twitter API has been deprecated:
https://developer.twitter.com/en/docs/twitter-for-websites/timelines/guides/collection.
lookup_collections(id, n = 200, parse = TRUE, token = NULL, ...)get_collections(
user = NULL,
status_id = NULL,
n = 200,
cursor = NULL,
parse = TRUE,
token = NULL
)
