KNIME Base Nodes version 4.0.2.v201909251340 by KNIME AG, Zurich, Switzerland
For each group an individual ranking is computed based on the selected ranking attribute(s) and ranking mode. The user must provide at least one attribute on which a ranking should be calculated.
The groups are determined by the unique value combinations of the grouping attribute(s). If no grouping attribute is provided, one ranking will be calculated for the whole table.
Missing values are considered to represent the largest value possible.
The columns in the input table will be called "attributes" to avoid confusion with the table structures in the dialog.
Ranking attributes can be added, removed and prioritized by the corresponding buttons. In order to change the selected attribute one can click on the name of a attribute to open a drop-down menu with all available attributes. The same applies for the ranking order, the options
The first attribute in the ranking table has the highest priority for ranking, all following attributes only come into play when there are ties in the attributes higher up in the table.
An attribute can be chosen by clicking on one of the attribute names in the table and selecting the desired attribute in the drop down menu.
For each attribute one can choose whether the ranking should be computed ascending or descending. To do so, click on the order for the corresponding ranking attribute and select the desired value.
Ranking attributes can be added and removed by the corresponding buttons.
An attribute can be chosen by clicking on an attribute name and selecting the desired attribute in the drop down menu.
