I have a CSV Reader node, then Table to R, but this node fails to connect to R Snippet. I am using a standard dataset - German Credit Risk (kaggle.com) and wanted to replace missing values using predictive mean matching (by pasting R code for that). How do I fix this?
NB: I have already set up the R server, which is running.
That’s not possible by design. Table to R has as output type R Workspace while R Snippet has table as input so the two cannot be linked. Have a look at these two pages where plenty of example workflows are posted which outline how both are being used.
No expert in R but based on your description I’d say R Snippet would be your choice.
@pmasuka2024 you might want to check this article and the examples to see how to work with knime and R. There are two integrations that require different approaches.
