As in topic. Here is the code:
ExcelExampleSource trainingData = OperatorServiceI try to apply this data to a model, but:
.createOperator(ExcelExampleSource.class);
trainingData.setParameter("excel_file", "audis_trainingData.xls");
trainingData.setParameter("create_label", "true");
trainingData.setParameter("label_column", "5");

Hi,
either use the configuration wizard or just load the data and insert another operator "set role" after this to identify the label attribute.

OPI thought of that before, but i simply can't find this operator. I know of it's presence in the actual RapidMiner program, but i can't find it in javadoc.

Hi,
because of historical reasons, the class names of the operators are not equivalent to the names inside the program. So if the operator is called "Set Role" one would assume the class would be called "SetRoleOperator" and I really would like that, but unfortunately it is called "ChangeAttributeRole". If you want to match an operators name to a class, take a look in the OperatorsCore.xml in the resource directory of RapidMiner. There the matching is done.

probably, because there's no such parameter in the operator?
