  test_dat = NULL, tree_control = list(p = 0.05, cp = 0.0001, xval = 1,
  maxdepth = 10), seed = 46)

Arguments

tree_fit

A tree model object.

train_dat

A data.frame of train.

target

The name of target variable.

test_dat

A data.frame of test.

tree_control

the list of parameters to control cutting initial breaks by decision tree.

seed

Examples

# NOT RUN {
train_test <- train_test_split(UCICreditCard, split_type = "Random", prop = 0.8, save_data = FALSE)
dat_train = train_test$train
dat_test = train_test$test
dat_train$default.payment.next.month = as.numeric(dat_train$default.payment.next.month)
get_ctree_rules(tree_fit = NULL, train_dat = dat_train[, 8:26],
target ="default.payment.next.month", test_dat = dat_test)

# }
