as.rpart: Conversion of a RevoScaleR rxDTree object to a rpart Object

Description

Converts objects containing decision tree results to a rpart object.

Usage

 ## S3 method for class `rxDTree':
as.rpart  (x, ...)

Arguments

x

object of class rxDTree.

...

additional arguments (currently not used).

Details

This function converts an existing object of class rxDTree an object of class rpart. The underlying structure of the output object will be a subset of that produced by an equivalent call to rpart. Often, this method can be used to coerce an object for use with the pmml package. RevoScaleR model objects that contain transforms or a transformFunc are not supported.

Value

an object of class rpart.

 ## Not run:

# If the pmml package is installed 
library(pmml)
infert.nrow <- nrow(infert)
infert.sub <- sample(infert.nrow, infert.nrow / 2)
infert.dtree <- rxDTree(case ~ age + parity + education + spontaneous + induced, 
   data = infert[infert.sub, ], cp = 0.01)
infert.dtree
pmml(as.rpart(infert.dtree))
