Are perhaps you looking for options(error = recover)?

No, not really. First I use this for non-interactive sessions (otherwise
I would mtrace() from package debug) and second I also want to save and
retrieve the environment contents in case there is no error which causes
R to stop.
Thanks, however, for your reply!

Dear R users,
I am using dump.frames() to investigate the content of the different
environments in cases of errors or during certain steps of a non interactive
calculation. I am, however, wondering about how to see the content of the
global environment at the moment that dump.fames() was invoked. Her is some
test piece (careful about the rm(list=ls(), remove the # if you know what you
are doing to easier see the effect):
# rm(list=ls())
a=2
test = function() {
b=3
dump.frames(dumpto='test', to.file = TRUE )
}
test()
# rm(list=ls())
load('test.rda')
debugger(test)
I can now investigate the value of 'b' but could not figure out a way to get
the value of 'a'. Am I missing something or is dump.frames only intended to be
uses with
options(error=dump.frames)
? Most probably some modification of save() would be more apropriate to use in
my case but I could not (yet) figure out how to mimic the convenient behaviour
of dump.frames() to save the whole call stack.
Thanks for any advice
Jannis
