R language: how to clear the frames/stack in Rstudio/console

By stack, I refer to the output from traceback() upon error condition. How does one 'clear the stack' so one gets 'No traceback available' from traceback()? thanks

Solution

  • It can be done by overwriting the .Traceback variable which is currently stored in the base namespace:

    stop("Hammer Time!")
Error: Hammer Time!
traceback()
1: stop("Hammer Time!")
assign(".Traceback",NULL,"package:base")
traceback()
No traceback available

    Be warned though:

    It is undocumented where .Traceback is stored nor that it is visible, and this is subject to change.
