There are a number of related versions of the Titanic data, in various

rpart.plot package, modifying it to remove the Class 'labelled'
attributes for some variables (inherited from Frank Harrell's
titanic3 version) which caused problems with some applications,
notably ggplot2.
Other versions:
Titanic is the 4-way frequency table of all 2201
people aboard the Titanic, including passengers and crew.
