Gary,
Was the second half of my message this morning not clear enough?
It wasn't clear from your original message that you were using isin()
from the prob package, rather than using isin() as pseudocode, so I'd
written a function to do that part. But the second half of my message
went through the if() part of your question. If it doesn't do what you
want, you need to be clearer about what you need that it doesn't do.
