options(error=utils::recover)
Does indeed work, at least with the new install of R-devel (to be 2.10.0)
that I am running right now. I was sure I checked this with 2.9.0 last
night, but I am probably mistaken.
One point, the ?options help page is misleading in that the example is "
Note that these need to
specified as e.g. 'options=utils::recover' in startup files
such as '.Rprofile'."
Since the use of "utils::" is a new requirement, I think stemming from when
utils is loaded, this help page should be corrected as the example is
confusing/incorrect.
So, stick with what is in the first line above and, for now, ignore the help
page.
