R help - Jul 2024 - [External] Using the pipe, |>, syntax with "names<-"

I think Iris's solution should be added to the help file: ?|>
there are no examples there now that show assignment or replacement using the
"_"

I second Rich's excellent suggestion.

As with all elegant solutions, Iris's clicked on the wee light bulb in
my brain, and I realized that a slightly more verbose, but perhaps
more enlightening, alternative may be:

z |>  attr("names") |> _[2] <- "foo"

However, I would add this as an example *only with* Iris's solution.
Hers should be shown whether or not the above is.

Cheers,
Bert
