Deb Garvey posed a question regarding picking off the value from the
head-of-household and applying it to a person in that family with
related==1114. If famunit is always 1 for heads-of-household, this
would seem to be simple--you don't really need to examine the value of
famunit for the head. But I imagine there's more to it than that. But
if every family has only one head (check with assert, perhaps), then
you can use something like the below to propagate the value to all
family members, and use it to replace only the 1114's. Slight
modification of Deb's sample data used here.
