[R] how to ignore errors

2008-12-01 Thread Jiang Peng 

 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 ))
}
