It's not about asking others to do it really, that was a harsh assumption.
I'd be happy to propose a version if it helps, I'd be also very happy if it
were just a copy of if_else or fifelse (both MIT FWIW).
It's a low level building block and it's broken, IMO it's way better to
have it available an
A package with only one function, what a concept!
But then it becomes tempting to also create a function like if_else_else() and
if_else_default() and of course if_not_else()
Joking aside, plenty of functionality in extendible languages like R were
written long enough ago that they might b
Dear r-devel,
`ifelse()` has a lot of issues, and for these reasons it has been redone in
`dplyr::if_else()` and `data.table::fifelse()`, which are both great. Yet
it's an important base R function, it's really hard to program in base R
without it and scores probably as high as it gets in the most
Rather than asking others to do this, why don't you create a tiny
package containing nothing other than an ifelse() replacement? I
wouldn't want to depend on dplyr or data.table just to get their
versions, but depending on your tiny package wouldn't be an issue.

I think Duncan's point is that R-core are (reasonably) very, very,
very conservative about adding things to base R. It would be useful to
the community, and would indeed further the discussion, to make a tiny
package containing just that function. (Even just copying it from some
other package
Avi, appreciate the puns!
I don't think anyone is suggesting R-core dedicate all of their time to
this problem.
To me, the thread is about consensus making (as there is no formal way to
do that).

Since you and Antoine are volunteering to do the work, why not start in
the way I suggested? Write up a comparison of the known ifelse
implementations, and either pick the best one, or choose the best parts
of each. Put the result in a package containing nothing else, and
