This node filters columns exclusively containing duplicates of the same value from the input data table. Examples include a column containing only zeroes, a column containing only identical Strings, or a column comprising only missing cells. In a dialog window, you can select which columns to apply the filter to (with all columns selected by default). From these selected columns, you can choose to remove either all constant value columns or columns containing only specific constant numeric, String, or missing values. Finally, you can also specify the minimum number of rows a table must have to be considered for filtering.
