Hi Duncan,
We haven't investigated yet, but I strongly suspect this is an RStudio issue.
For extra context, RStudio is doing something similar to R's own
staged installation here, where the package is initially installed
into a _build sub-directory, and then moved to its final intended
installati
... and of course, immediately after clicking send, I realize you're
using macOS, not Windows. I don't think we need this sub-directory
approach on non-Windows operating systems, so if that's affecting the
behaviour here, that's surely an RStudio bug.
