For each row in my table, I’d like to find the most common value across certain “destination” columns. The result would then appear in another column, “Mode Destination”. So:
KNIME recognises that all columns contain strings.
Using the GroupBy node, I can select the columns I want to use in the Groups tab. I then go into the Manual Aggregation tab, add “Mode Destination”, and set the aggregation operator to Mode.
However, when I run the node, my “Mode Destination” column is blank. What am I doing wrong?
