Working With Collections - Supported nodes

The goal of the workflow is to demonstrate the creation and working with collection cells. It is divided into three parts.
The last section "Working with collections" demonstrates a sub set of the nodes that support collections such as the Item Set Finder (Borgelt) node which searches in a collection column for frequently co-occuring elements.

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.
