extracting predictors from ctree object

Question

I\'ve checked binary tree class methods, and How to extract tree structure from ctree function? (which was helpful understanding S4 object structure and slots),

Answer 1

split <- 
c(cart@tree$psplit$splitpoint , cart@tree$right$psplit$splitpoint , cart@tree$left$psplit$splitpoint , cart@tree$right$right$psplit$splitpoint , cart@tree$right$left$psplit$splitpoint , cart@tree$left$right$psplit$splitpoint , cart@tree$left$left$psplit$splitpoint , cart@tree$right$right$right$psplit$splitpoint , cart@tree$right$right$left$psplit$splitpoint , cart@tree$right$left$right$psplit$splitpoint , cart@tree$right$left$left$psplit$splitpoint , cart@tree$left$right$right$psplit$splitpoint , cart@tree$left$right$left$psplit$splitpoint , cart@tree$left$left$right$psplit$splitpoint , cart@tree$left$left$left$psplit$splitpoint , cart@tree$right$right$right$right$psplit$splitpoint , cart@tree$right$right$right$left$psplit$splitpoint , cart@tree$right$right$left$right$psplit$splitpoint , cart@tree$right$right$left$left$psplit$splitpoint , cart@tree$right$left$right$right$psplit$splitpoint , cart@tree$right$left$right$left$psplit$splitpoint , cart@tree$right$left$left$right$psplit$splitpoint , cart@tree$right$left$left$left$psplit$splitpoint , cart@tree$left$right$right$right$psplit$splitpoint , cart@tree$left$right$right$left$psplit$splitpoint , cart@tree$left$right$left$right$psplit$splitpoint , cart@tree$left$right$left$left$psplit$splitpoint , cart@tree$left$left$right$right$psplit$splitpoint , cart@tree$left$left$right$left$psplit$splitpoint , cart@tree$left$left$left$right$psplit$splitpoint , cart@tree$left$left$left$left$psplit$splitpoint , cart@tree$left$left$left$left$left$psplit$splitpoint , cart@tree$left$left$left$left$right$psplit$splitpoint , cart@tree$left$left$left$right$left$psplit$splitpoint , cart@tree$left$left$left$right$right$psplit$splitpoint , cart@tree$left$left$right$left$left$psplit$splitpoint , cart@tree$left$left$right$left$right$psplit$splitpoint , cart@tree$left$left$right$right$left$psplit$splitpoint , cart@tree$left$left$right$right$right$psplit$splitpoint , cart@tree$left$right$left$left$left$psplit$splitpoint , cart@tree$left$right$left$left$right$psplit$splitpoint , cart@tree$left$right$left$right$left$psplit$splitpoint , cart@tree$left$right$left$right$right$psplit$splitpoint , cart@tree$left$right$right$left$left$psplit$splitpoint , cart@tree$left$right$right$left$right$psplit$splitpoint , cart@tree$left$right$right$right$left$psplit$splitpoint , cart@tree$left$right$right$right$right$psplit$splitpoint , cart@tree$right$left$left$left$left$psplit$splitpoint , cart@tree$right$left$left$left$right$psplit$splitpoint , cart@tree$right$left$left$right$left$psplit$splitpoint , cart@tree$right$left$left$right$right$psplit$splitpoint , cart@tree$right$left$right$left$left$psplit$splitpoint , cart@tree$right$left$right$left$right$psplit$splitpoint , cart@tree$right$left$right$right$left$psplit$splitpoint , cart@tree$right$left$right$right$right$psplit$splitpoint , cart@tree$right$right$left$left$left$psplit$splitpoint , cart@tree$right$right$left$left$right$psplit$splitpoint , cart@tree$right$right$left$right$left$psplit$splitpoint , cart@tree$right$right$left$right$right$psplit$splitpoint , cart@tree$right$right$right$left$left$psplit$splitpoint , cart@tree$right$right$right$left$right$psplit$splitpoint , cart@tree$right$right$right$right$left$psplit$splitpoint , cart@tree$right$right$right$right$right$psplit$splitpoint)

split <- split[order(split)]
