Dear listers, Hi . I googled before I ask this question in case to avoid violating the "list law". The question was proposed by somebody else but nobody gives a proper solution. How to ignore errors in a R loop? I have a R source file ,namely, test.r. I ran a loop in a command line
> for(i in 1 : 100 ) {source("test.r",echo =T ) }
and I found that when test.r have some error the loop will stop, but test.r is just stochastically wrong,i.e., sometimes it works well if no bad values return. I want to know how to ignore such errors and let the loop continue. thanks in advance.

Jiang Peng,
The default solution is using try command, something like this
for(i in 1 : 100 ) {
try(source("test.r",echo =T ))
}
