R help - Aug 2005 - error tracing

Hi, I am running some Cox modeling on large number of
variables (thousands) using apply. For some reasons,
some of the variables have problems in Cox regression,
so the the run was stopped automatically. Is there a
way to keep the running for all the variables to
complete and let us, when done, to trace back which of
the variables cause the problem?

Thanks

Since each Cox model is a bit of work, you won't notice
the difference if you used a loop instead of apply. Within the for-loop, 
use try() to catch the bad guys.
