Working With Collections - Collection creation and conversion
The goal of the workflow is to demonstrate the creation and working with collection cells. It is divided into three parts. The "Collection creation and conversion" part shows how collection columns can be generated by combining rows e.g. by grouping them in the GroupBy node or columns e.g. by combining them in the Column Aggregator node. Required plugins: - KNIME Itemset Mining (contains the Item Set Finder (Borgelt) node) General Information Press the green double arrow above to run the complete workflow. The KNIME data table outport view displays by default only the first part of a collection cell. If you want to view all elements of a collection change the cell renderer via the column context menu. To open the context menu click with the right mouse button on the column header e.g. (...)Characters in the table outport view of the top left GroupBy node. Select the Collection(full) renderer from the available renderes. Notice other data types allow you to change the cell renderer as well e.g. multi line renderer for string or full precission renderer for double values.
