As Thomas Lumley has noted before, the behavior in 'batch mode' has changed;

I think this is THE good default behavior for "batch mode".
However
1) for several purposes I'd very much want an option to change this
default behavior.
Hear, hear!
I think it'd be very neat then if options(error.stop = FALSE) actually translated all errors [stop(.)] to warnings [warning()].
I'm not convinced. Being able to make warnings fatal is a good option, but being able to continue after errors may make no sense. How do you continue after subscript out of bounds, or argument missing with no default, or memory exhausted or ... You may well need to jump back to the top level before it makes sense to continue. On the other hand, once at the top level it is certainly possible to proceed, and so there should be an option to do it.
