| 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.
