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 ------------ próxima parte ------------ Se ha borrado un adjunto en formato HTML...
