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.
