PMML and R


I have to create a pmml on a data that includes preprocessing steps  learned on randomForest. As far as I understand there is no such workflow in KNIME - saving the transformation along the pmml by using RandomForest. I can do it within R Learner using pmml and pmmlTransformations but the output port of the R Learner takes only the fitted model so R To PMML Node is not good since it will not take into account the transformation. Any ideas how to overcome this defficiency now ?



You are probably using the "old" R integration in KNIME, with the new interactive R (labs) extension you have more flexibility by configuring the R To PMML node in order to translate your R model/workspace into an PMML object.
