Adding more ports to R node

Is there a way to add more ports to the R node?
I have 2 tables that I want to transform using R code


Hi @thentangler

Do your tables have the same structures? I would suggest to concatenate both Query readers into one table (Concatenate node), before passing it to the Table to R node, then finally pass that one output to the R to R.

I can’t provide you an example right now because a don’t have those extensions installed. I hope my suggestion makes sense.

@thentangler you could add another table to R with this node (example here)

Or you could save data in a parquet file or SQLite database and use that in the R node (and also bring data back to knime)


@mlauber71 and @eamendola thank you for these suggestions. It’s working now!
