An instance filter that adds a new attribute to the dataset. The new attribute will contain all missing values.
Valid options are:
-T <NUM|NOM|STR|DAT> The type of attribute to create: NUM = Numeric attribute NOM = Nominal attribute STR = String attribute DAT = Date attribute (default: NUM)
-C <index> Specify where to insert the column. First and last are valid indexes.(default: last)
-N <name> Name of the new attribute. (default: 'Unnamed')
-L <label1,label2,...> Create nominal attribute with given labels (default: numeric attribute)
-F <format> The format of the date values (see ISO-8601) (default: yyyy-MM-dd'T'HH:mm:ss)
