| print.rpart {rpart} | R Documentation |
This function prints an rpart object. It is a method for the generic
function print of class rpart.
## S3 method for class 'rpart':
print(x, minlength=0, spaces=2, cp, digits= getOption("digits"), ...)
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. |
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.
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 probabilties are also printed.
