Thanks for explanation, so recover in non-interactive session exit
with 0 is expected behavior .
dump.frames said that it always write to file (workspace , or specified file).
I have a R script run as a auto build stage, so I want to print detail
backtrace to console
(with source file, line number) for quickly debug, without saving any dump.
I tried
options(error= quote({utils::recover;q(status=1)}))
it do exit with 1 when script has error, but it only shows a stripped
call trace like
Calls: a ... a -> a -> a -> a -> a -> a -> a -> a -> a -> a -> apply
instead of
...
99: rec.R#5: a(v, depth - 1)
100: rec.R#5: a(v, depth - 1)
101: rec.R#5: a(v, depth - 1)
102: rec.R#5: a(v, depth - 1)
103: rec.R#5: a(v, depth - 1)
How can I resolve this ? Thanks for advise
