Hello, How can I transfer the result of the “Linear Regression Learner Node” with “Multiple R-Squared” and “Adjusted R-Squared” into the “Table View-Node”.

Basically I want to display all values of “View:Linear Regression Result view” via the "Table View node.

Hmm…
The only way I know of is attaching the “Numeric Scorer” node to the Regression Predictor node. E.g.:

But that does not get you the Adjusted R-Squared value.

Alternatively, I would recommend doing your regression in an R-Snippet node and outputting the results as a data frame. (Use the table-to-R node to set up the regression, then the R-to-table node to get the results back into the workflow loop.)

There are better ways to do this I’m sure, but most of the examples I saw required additional packages (what doesn’t need a package in R?!). This is just with base R. You could probably get creative and concatenate them into a single table if you would like, but I’ll leave the rest to you

I have not tested the solution (with R), because I want to realize everything directly in Knime and
don’t want to get into the dependency hell.
–>If there is a direct solution in Knime, then I would be grateful if I could get another suggestion for this.

Thank you @stelfrich for this solution. But if there are missing values in my dataset, then the node “Enhanced Numeric Scorer” does not work.
And the following error message appears: §Execute failed: Missing value in prediction column in row: Row23".
(the node “Linear Regression Learner” works without problems with the data set and outputs also R2 etc.).
Can you give me a hint how to get the “Enhanced Numeric Scorer” to work despite missing values?

Unfortunately, I don’t have enough time to look into making the component more robust right now. You can, however, use the Missing Value node to remove the rows that contain missing values before feeding them to the Enhanced Numeric Scorer component. Ideally, you would configure the node such that it removes all the rows that have missing values in the feature columns:
