Nominal Value Row Splitter

Splits the rows based on the selected value of a nominal attribute. A nominal column can be selected and one or more nominal values of this attribute. Rows which have this nominal value in the selected column are included in the output data in the first table, the rest in the second.

In order for a nominal column to appear in the node dialog, its domain (the set of values that appear in the column) must be calculated. For columns with few values (less than 60) this is done automatically. To ensure the domain is properly set, use the Domain Calculator node or the Edit Nominal Domain node.

Options

Filter column
Select the column containing the nominal values to be filtered.
Values
Select the nominal values to be in the first output table, by moving them from left (second table) to right (first table).
If value is missing
Defines how missing values are handled.
  • Second: Missing values are excluded from the first output table. They will be included in the second table instead.
  • First: Missing values will be included in the first output table.
