For this version of the Titanic data,
passenger details and incomplete cases were deleted
and the name changed to etitanic to minimize confusion with other
versions ("e" because it is part of the earth package).
Note that survived is an integer (it should arguably be a logical).
In this data the crew are conspicuous by their absence.
