[R-pkg-devel] no visible global function definition

[Kevin Ushey]

Hi Uwe,

It seems like this is quite a major change; I imagine it will affect many
packages (since lots of packages implicitly assume other 'base' packages,
like 'utils', will always be available in an R session). IIUC, in the
latest versions of R-devel, only the 'base' package can be assumed
available; everything else must be explicitly imported.

https://github.com/wch/r-source/commit/dba5a49dcae7e9bcb8528cf78fd9d51f092652b2

Is there any chance that such changes could be made in announcements on
R-pkg-devel? Or, as an aside, would it be permissible for non-R-core
members to make such announcements on this list?

Thanks,
Kevin
