Edit Nominal Domain
Resorts and/or inserts interactively possible values to the
domain
of a
certain column
of the input table. This allows the configuration
of
downstream
nodes on an amended domain list,
e.g. a histogram that
should show an empty bin for a value that is not
actually present in
the data. Also,
the sorting on the domain values can be changed. This
might be useful
for instance for many predictor nodes,
which add a new
column for each possible value to the prediction output
table,
whereby the order of the
columns is determined by the ordering in the
domain.
Dialog Options
- Select column
-
Selects the column for which the domain values
should be edited.
Non-string typed
columns are filtered out. A column name with red border indicates that the
domain values for this
columns were previously configured but the column either no longer
exists or has a different type (no string column anymore). Red written
domain value orderings can
be edited
as
others and in addition deleted.
(See the
Reset/Delete
option)
- Add
-
Creates a new cell with the given value and
inserts it at the selected
position. Self created cells are
green
marked in the possible value list.
- Remove
-
Removes all selected self created cells (green
marked)
or cells which are not contained in the possible
value set of
the original column specification (red marked). It is not
possible to
remove
other possible values, i.e. the possible values defined by the
original column specification, as that might corrupt the table
consistency.
- Sort alphabetical [A-Z, Z-A]
-
Sorts the elements in alphabetical order ascending
(A-Z)
or descending (Z-A).
- Move one step [Up, Down]
-
Moves the selected element(s) one up or down. If
the top or the bottom
of the list is reached, the selected element(s)
is/are enqueued on the
other end of the table again.
- Move first/last
-
Moves the selected element(s) to the top or at the
end of the table.
- Reset/Delete
-
Restores the original domain value list as in the
input table. If a not existing but previously configured column is
selected (written in red), this button is labeled
with 'Delete' and
deletes the stored configuration for the selected column.
- If a configured columns is not present in data
-
Determines if the execution should either fail or
the column should be ignored if a configured column does not exist in
the input table.
- If a configured columns has an incompatible type
-
Determines if the execution should either fail or
the column should be ignored if
the types of a configured column are
not equal.
