Keywords
tree
##### Usage
# S3 method for rpart
print(x, minlength = 0, spaces = 2, cp, digits = getOption("digits"), …)
##### Arguments
x

fitted model object of class "rpart". This is assumed to be the result of some function that produces an object with the same named components as that returned by the rpart function.

minlength

Controls the abbreviation of labels: see labels.rpart.

spaces

the number of spaces to indent nodes of increasing depth.

digits

the number of digits of numbers to print.

cp

prune all nodes with a complexity less than cp from the printout. Ignored if unspecified.

arguments to be passed to or from other methods.

##### Details

This function is a method for the generic function print for class "rpart". It can be invoked by calling print for an object of the appropriate class, or directly by calling print.rpart regardless of the class of the object.

##### Side Effects

A semi-graphical layout of the contents of x\$frame is printed. Indentation is used to convey the tree topology. Information for each node includes the node number, split, size, deviance, and fitted value. For the "class" method, the class probabilities are also printed.
