Titanic data with incomplete cases, passenger names, and other details removed.
Format

pclass | passenger class, unordered factor: 1st 2nd 3rd |
survived | integer: 0 or 1 |
sex | unordered factor: male female |
age | age in years, min 0.167 max 80.0 |
sibsp | number of siblings or spouses aboard, integer: 0...8 |
parch | number of parents or children aboard, integer: 0...6 |
Source
This dataset is included in the earth package because it is a convenient vehicle for illustrating earth's GLM and factor handling.
The dataset was compiled by Frank Harrell and Robert Dawson:
https://hbiostat.org/data/repo/titanic.html
See also:
https://biostat.app.vumc.org/wiki/pub/Main/DataSets/titanic3info.txt.
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.

How etitanic was built:
load("titanic3") # from Harrell's web site
# discard name, ticket, fare, cabin, embarked, body, home.dest
etitanic <- titanic3[,c(1,2,4,5,6,7)]
etitanic <- etitanic[!is.na(etitanic$age),]
save(etitanic, file="etitanic.rda")
