Coercion Functions

Description

Functions coercing various objects to objects of class party.

Usage

as.party(obj, ...)
## S3 method for class 'rpart'
as.party(obj, data = TRUE, ...)
## S3 method for class 'Weka_tree'
as.party(obj, data = TRUE, ...)
## S3 method for class 'XMLNode'
as.party(obj, ...)
pmmlTreeModel(file, ...)
as.constparty(obj, ...)
as.simpleparty(obj, ...)
## S3 method for class 'party'
as.simpleparty(obj, ...)
## S3 method for class 'simpleparty'
as.simpleparty(obj, ...)
## S3 method for class 'constparty'
as.simpleparty(obj, ...)
## S3 method for class 'XMLNode'
as.simpleparty(obj, ...)

Arguments

obj

an object of class rpart, Weka_tree, XMLnode or objects inheriting from party.
data

logical. Should the model frame associated with the fitted obj be included in the data of the party?
file

a file name of a XML file containing a PMML description of a tree.
...

additional arguments.

Details

Trees fitted using functions rpart or J48 are coerced to party objects. By default, objects of class constparty are returned.

When information about the learning sample is available, party objects can be coerced to objects of class constparty or simpleparty (see party for details).

Value

All methods return objects of class party.

Examples

## fit tree using rpart
library("rpart")
rp <- rpart(Kyphosis ~ Age + Number + Start, data = kyphosis)

## coerce to `constparty'
as.party(rp)
