Reads a 'wide' CSV files into a KNIME vector format. In comparison to the standard CSV Reader or FileReader the output of this node will comprise a KNIME vector format, which can host many numeric values (tens of thousands). A typical file to read will have a format similar to
1.0, 0.0, 3.7, ... <many more values>, "class A" 3.0, 0.0, 1.0, ... <many more values>, "class B"
The numeric columns at the beginning of each line are then collected into a single collection column, which can be efficiently handled by the KNIME framework at the expense of not being usable by some of the preprocessing nodes.
Note: Most users will want to use the File Reader or CSV Reader unless they have wide data.
