Review Comment:
@assignUser It's here:
https://arrow.apache.org/docs/r/articles/install.html?q=install_arrow#using-install_arrow
> Although this function is part of the arrow package, it is also available
as a standalone script, so you can access it without first installing the
package:
In the case of "You want to install a development build", folks may not
already have arrow installed.
On a different note, there have been other PRs in this area of the codebase
merged recently, so this PR may need a rebase to see how the changes affect it,
and what needs doing.
