etitanic {earth} | R Documentation

## Titanic data with incomplete cases removed

### Description

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

### Format

A data frame with 1046 observations on 6 variables.

`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: http://biostat.mc.vanderbilt.edu/twiki/pub/Main/DataSets/titanic.html

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")
