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

[Marius Hofert]

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.

Cheers,

Marius
