Why won't "fdeaths/mdeaths" datasets load?

[Helpingmeisfun]

Was just trying to work my way through the new (very promising) fable package, and wanted to reproduce the example here, that uses monthly UK lung deaths. The "tsibbledata" package shown in the linked page doesn't seem to exist, but the "datasets" package has datasets called "fdeaths" and "mdeaths" that I thought I could use instead. What could be simpler?

I have loaded the datasets package, and when I run data(), both show up in the list. Yet, if I try to load them, e.g., "data(fdeaths)" plus literally every possible variation on that I can think of, I get an error:

data(fdeaths) 
Warning message: In data(fdeaths) : data set ‘fdeaths’ not found

Whyeeeeee? I'm baffled. I know I could just move on and pick from many other time series datasets, but I have to figure it out.

Sorry in advance for whichever of the question-asking infractions I've committed. Happy to amend in any way that will be productive, but I really didn't think this needed actual code or a reprex. Imagine every possible way you would try to load that dataset, and I've probably tried it and gotten the exact same error.

Thanks!

Try loading data from base datasets.

Thanks! I found it also works to do data(UKLungDeaths), but I still don't understand why that doesn't autocomplete like all other datasets. I had tried it, but waved off when it didn't show up. Weird, but I'm sure there's a reason.
