There has been a bit of discussion on here about ‘nothing’ vs ‘missing’ and why both are needed. I don’t really have an opinion on this as long as I can easily convert, which I can’t.
I tried the suggestion on Github [missing vs nothing #1854] which was marked as the solution:
replace( df.A , nothing => missing)
and it didn’t complain but didn’t work (‘nothings’ still there).
I wondered why the ! wasn’t needed and also why I didn’t need to broadcast, but attempting either of those led to an error.
Does anyone have any ideas?
