Extracts a column or row of data from a weka.core.Instances or SpreadSheet object.
Only numeric columns can be returned. In case of row-retrieval, the value of the internal format of the weka.core.Instance object is returned; for SpreadSheet object it is attempted to convert the cell content to double (null values might get returned!).
