You can use a calling handler along with sys.calls, something like
f <- function() g()
g <- function() stop("A")
tryCatch(withCallingHandlers(f(),
error = function(e) {
e$calls <- sys.calls()
signalCondition(e)
}),
error = function(e) e)

Hi all,
The help for traceback states:
Errors which are caught _via_ 'try' or 'tryCatch' do not generate
a traceback, so what is printed is the call sequence for the last
uncaught error, and not necessarily for the last error.
Is there any way to get a traceback (or something similar) for an
error raised inside a try block?
Regards,
Hadley
