To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The combination of some data and an aching desire for an answer does not

Onderwerp: [R] ignore error in for-loop

Hi all,

Can anybody tell me what to do in case an error occurs inside a 
for-loop and I don't want the program to exit the loop? Rather 
instead I would like it to just go to the next number in the loop and 
try again with the new number. Is there any function like "on error 
go back to" or "skip error" ... ?

Thanks in advance,
Erich
