Survival of passengers on the Titanic

Description:

     This data set provides information on the fate of passengers on
     the fatal maiden voyage of the ocean liner 'Titanic', summarized
     according to economic status (class), sex, age and survival.

Usage:

     Titanic

Format:

     A 4-dimensional array resulting from cross-tabulating 2201
     observations on 4 variables.  The variables and their levels are
     as follows:

       No  Name      Levels
        1  Class     1st, 2nd, 3rd, Crew
        2  Sex       Male, Female
        3  Age       Child, Adult
        4  Survived  No, Yes

Details:

     The sinking of the Titanic is a famous event, and new books are
     still being published about it.  Many well-known facts-from the
     proportions of first-class passengers to the 'women and children
     first' policy, and the fact that that policy was not entirely
     successful in saving the women and children in the third class-are
     reflected in the survival rates for various classes of passenger.

     These data were originally collected by the British Board of Trade
     in their investigation of the sinking.  Note that there is not
     complete agreement among primary sources as to the exact numbers
     on board, rescued, or lost.

     Due in particular to the very successful film 'Titanic', the last
     years saw a rise in public interest in the Titanic.  Very detailed
     data about the passengers is now available on the Internet, at
     sites such as _Encyclopedia Titanica_ (<URL:
     http://www.rmplc.co.uk/eduweb/sites/phind>).

     mosaicplot(Titanic, main = "Survival on the Titanic")
     ## Higher survival rates in children?
     apply(Titanic, c(3, 4), sum)
     ## Higher survival rates in females?
     apply(Titanic, c(2, 4), sum)
