Hi all,

 

Does any of you know how to make a decision tree when the data set contains 
factors and numericals?

I've got a data frame with 3 columns, where y and x1 are numerical and x2 
contains factors. Is it possible to use the rpart package, and in that case 
how? Otherwise, is there another alternative?

 

This is what I've tried so far

 

> rpart(LT50_NA ~ Raf + Antho, data=decTreeNA, method=anova) # Have tried 
> "method=class" as well
Error in as.character(x) : 
  cannot coerce type 'closure' to vector of type 'character'

 

Best regards,

 

Joel
