withCallingHandlers() lets you evaluate expressions with code to catch messages, warnings and errors. I don't know if there's a way to evaluate every expression entered at the console within withCallingHandlers() for an effect like options(error=), but you can certainly write code to read a file and evaluate every expression in it within a withCallingHandlers() call.
