[R] How to *completely* stop a script after stop()?

[Carl Witthoft]

Somehow this reminds me of a famous FORTRAN code snippet:

10 STOP
STOP
STOP
! IN CASE STILL SKIDDING
GOTO 10

Dear expeRts,

is there a neat way to *completely* stop a script after an error 
occured? For example, consider the following script:

## ==== file.R ====

for(i in 1:10){

	print(i)
	if(i == 5) stop("i == 5")


}
for(i in 11:100) print(i)

## ================


stop() behaves like it should namely to stop the execution of the 
*current* expression, but I was wondering if it is possible to *really* 
stop the script after the first for loop [so without executing the 
second for loop or anything after that point]. Of course one could use 
something like "if(there was an error) do not continue" but that's not 
really nice.
