There are a variety of ways to do this,
from the options help:
error: an expression governing the handling of non-catastrophic
errors such as those generated by `stop'' as well as by
signals and internally detected errors. The default
expression is `NULL'': see `stop'' for the behaviour

that allows post-mortem debugging.
show.error.messages: a logical. Should error messages be printed?
Intended for use with `try'' or a user-installed error
