How to *completely* stop a script after stop()?
Hi Carl,
If you wrap the whole script in brackets the script will not proceed
past the stop() function:
{
for(i in 1:10){
print(i)
if(i == 5) stop("i == 5")
}
for(i in 11:100) print(i)
}
best,
Ista

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.
