totoUp <- function(x) {
   totoDown(x)
   print("finish")
}
totoDown <- function(x) {
   if(x == "stop")
      stop("The function has been killed")
}

[sylvainschmitt]

totoUp("0")
[1] "finish"
totoUp("stop")
Error in totoDown(x) : The function has been killed

Have a look to the try and catch functions

[VincyaneBadouard]

[speaking informations]
"try" : try the internal function without kill the upper function
"catch" : catch the result

"stop" is an error function, if it's just a prerequisites question, use "if" not "stop"

Response -> yes, "stop" in an internal function stop the upper function
