[R] Automatic traceback

[Michael Hoffman]

I would like to have an automatic traceback printed on error. Is there
a way to do this?

options(error=traceback) seems to print the previous error, not the
current error. I'm guessing this is because the traceback is not set
until the error handler is done running.

> options(error=traceback)
> stop("1")
Error: 1
No traceback available
> stop("2")
Error: 2
1: stop("1")
> stop("3")
Error: 3
1: stop("2")

I am using R version 2.6.0 (2007-10-03).
