Thanks, you who responded; this was exactly helpful, and a good
reference to the part of the FM I was missing.  To unpack (and
demonstrate some comprehension gained.. ;) the subsetting operations
on data frames, by default, use the most basic data type capable of
representing the answer.  

Either the drop=FALSE or the inputs[targets] solution give me the
result I had in mind.  I mildly prefer the [targets] statement from a
visual perspective.
