rstudio's traceback() does not work interactively anymore

Question

I just started with debugging in rstudio. At the beginning everything worked as described here.

After I used browser(), I cannot get back to this status, that means there is no interactive field, where I can press the hide traceback or return with debug button. Does anybody know, what is going wrong?

Suggestions above do not work.
traceback() works but the message is not interactive anymore.
options(error = function(){.rs.breakOnError(TRUE)}) from here https://support.rstudio.com/hc/en-us/community/posts/202296047-error-recovery sets the value to TRUE, but still no interactive traceback appears.

RStudio Version

os mingw32
system x86_64, mingw32

Please let me know if you also need all options() settings.

Edit November 2018: Run a script with an error an interactive traceback active.

getOption("error")
(function () 
{
    .rs.recordTraceback(FALSE, 5, .rs.enqueueError)
})()

Destroy interactive traceback (No idea, what I did):

getOption("error")
(function () 
{
    .rs.recordTraceback(FALSE, 5, .rs.enqueueError)
})()

Thus, settings are the same and it unclear what happens...

Unfortunately, my suggestion didn't stick for me either, so I've deleted my answer. :-( — Tripartio, Nov 28 '18 at 15:50

I had the same behavior. After programmatically setting the error option in R to browser, traceback or recover, the button in RStudio (Debug/On Error) didn't work anymore.

To resolve this I had to first reset the error option to it's default value NULL. After that I could get back the interactive debugger.

The following resets the option first to NULL and then sets the option to the behavior that you get with selecting (Debug/On Error/Error Inspector) in RStudio.

options(error = NULL)
options(error = function(){.rs.recordTraceback(TRUE)})

The following works for me: 1. options(error = NULL) 2. RStudio => Debug => On Error => Error Inspector However, it only works ONCE. Afterwards I have to do the same process again to make it work again. The following does not work: 1. options(error = NULL) 2. options(error = function(){.rs.recordTraceback(TRUE)}) – Christoph Apr 12 '16 at 07:34

Running options(error = traceback) in console will output the traceback messages, but it will not work after restart RStudio. That is, you need to run options(error = traceback) every time launching RStudio.
