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.
