'options=utils::recover' not working in .Rprofile or within R

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.

You are wiping out all of the default options with that approach.

Try (after restarting R to get the other options back to what they should
be):

op=options()                   # so you can reset back to baseline
options(error=utils::recover)  # do not think the "utils::" is needed
 my.func <- function(x){
 y <- x + 12
 nonsense
 y
 }

 my.func(14)
Error in my.func(14) : object "nonsense" not found

Enter a frame number, or 0 to exit

1: my.func(14)

 Duncan,
    

I've pared down my .Rprofile so that it has just the options line, started
R
from terminal (instead of using ESS-emacs) and I still have the problem.
Am
I specifying the options incorrectly? I believe I took this directly from
the help page.

      

Not what the examples look like on my machine.


 See my output of .Rprofile, the code example that doesn't
    

work as we think it ought, and my sessionInfo().  Thanks, Mark

Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.
