Decision trees with factors and numericals
...he 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 _______________________________________________________________...
