How ptitanic
was built:
load("titanic3.sav") # from Dr. Harrell's web site
# discard name, ticket, fare, cabin, embarked, body, home.dest
ptitanic <- titanic3[,c(1,2,4,5,6,7)]
# change survived from integer to factor
ptitanic$survived <- factor(ptitanic$survived, labels=c("died", "survived"))
save(ptitanic, file="ptitanic.rda")
This version of the data differs from
etitanic
in the earth
package
in that here survived
is a factor (not an integer)
and age
has some NA
