Hi R-users,
How to get a bug contex?
My R code ran there for several hours, but a bug crashed it, printing
such message like "Error: subscript out of bounds". I want to use
browser() to catch the bug, but I don't know which loop caused the bug
(there are many loops in the code). I even don't know which line of
code caused the bug. Is there any utility or something in R which can
let you know which line of code causes a bug?
No, but ...
Have you tried traceback() to see which function is the culprit?
You can also set options(error = recover) to look at the objects at the
time the error occured. Maybe you see which object is already defined
and can derive the point of the error that way.
