R help es - Aug 2016 - Chaid

Hi,


I am running a chaid tree using titanic dataset (see attachment)



setwd("C:/Users/miguel")

titanic <- read.csv("train.csv")
titanic.s <- subset( titanic, select = -c(PassengerId, Name ) )

ctrl <- chaid_control(minsplit = 20, minbucket = 5, minprob = 0)
chaidTitanic <- chaid(Survived ~ ., data = titanic, control = ctrl)



It looks like I get the following error

Error: is.factor(x) is not TRUE



can you please help me here? I am not able to follow this type of error.


Thanks

Do
factor(Survived)
when calling chaid(...)
Best,
