There are a number of related versions of the Titanic data, in various formats.
This version was derived from ptitanic in the rpart.plot package,

(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.
