An example of this warning is shown on this RPubs page.
## Warning: `as_data_frame()` is deprecated as of tibble 2.0.0.
## Please use `as_tibble()` instead.
## The signature and semantics have changed, see `?as_tibble`.
## This warning is displayed once every 8 hours.
## Call `lifecycle::last_warnings()` to see where this warning was generated.
While being well-intentioned, this warning can come from somewhere in a large data pipeline and the fix may not be as simple as using "as_tibble" instead of "as_data_frame" as suggested -- because I'm not using "as_data_frame" anywhere in my code. So, I make what I suspect is a likely fix (in my case a column name was assigned to be ""), but then I cannot test the fix until 8 hours has passed?
How can I force this warning to always appear so I can immediately know I fixed the problem and have eliminated the warning instead of waiting 8 hours to verify?
