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

you could always do this

 getOption(showWarnCalls, FALSE)
 getOption(showErrorCalls, FALSE)

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.
