R help - Dec 2021 - checkpointing

Has anyone ever considered what it would take to implement checkpointing in R,
so that long-running processes could be interrupted and resumed later, from a
different process or even a different machine?

Thanks,

Andy

This sounds like an OS feature, not an R feature... certainly not a portable R
feature.

Sent from my phone. Please excuse my brevity.

Use VirtualBox.  You can take a 'snapshot' of a running virtual
machine, either from the GUI or from the CLI (vboxmanage snapshot ...)
and restore it later.

This requires NO changes to R.  Snapshots can be restored on
another machine of the same kind with the same system software.

VirtualBox is free.  Parallels is (just) under USD100.
