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.

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...

Answer 1

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)})
