[R] Error in { : task 3 failed - "NA/NaN argument"

[Maas James Dr (MED)]

I'm attempting to run a rather complex routine that involves a few loops, and even some use of foreach and doMPI.  I just added another external loop and now get this error message.

Error in { : task 3 failed - "NA/NaN argument"

Is there a way to debug what is causing this error or where?  I really have no idea what "task 3" is?

Thanks

Jim
