dear ERic, Thanks for your reply. As mentioned, I will post my issue in the R devel list.

After reading Bert's comment I checked the posting guide for this list and I see that a better fit for your question would be the r-devel list. https://stat.ethz.ch/mailman/listinfo/r-devel Best, Eric On Tue, Feb 15, 2022 at 6:37 PM Bert Gunter <bgunter.4...@gmail.com> wrote: > > 1.
