You don't tell us anything about your platform or how
you are creating the R session.
But yes, R is designed when running in non-interactive mode
to quit when there is an error.
There are different things you can do to get the desired
behaviour. I suggest you send mail to r-devel as this
is not just an R-sig-gui question.
