extensionoutputnode properties

Extension Output node iconWith the Extension Output node, you can analyze data and the results of model scoring using your own custom R or Python for Spark script. The output of the analysis can be text or graphical.

Note that many of the properties on this page are for streams from SPSS Modeler desktop.

Python for Spark example

import modeler.api
stream = modeler.script.stream()
node = stream.create("extension_output", "extension_output")
node.setPropertyValue("syntax_type", "Python")

python_script = """
import json
import spss.pyspark.runtime

cxt = spss.pyspark.runtime.getContext()
df = cxt.getSparkInputData()
schema = df.dtypes[:]
print df
"""

node.setPropertyValue("python_syntax", python_script)

R example

node.setPropertyValue("syntax_type", "R")
node.setPropertyValue("r_syntax", "print(modelerData$Age)")
