R To PMML

I'm trying to us an R to PMML node to convert a model. I know the code works in R, but i'm getting the following error in my R to PMML node:

Execution Failed: Execution of R script failed:Calls:write -> cat

 

 

The code:

 

library(pmml)

knime.out <-pmml(irisLR)

I assume you are generating a "LR" model whatever that is. I don't think it can be supported into PMML (for a complete list see dmg.org).
