| 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.
