This command encodes a given classified data related to a source data. For each class a new binary variable is created. Then the index of each data record is matched to the indexes in the class. If an index is found the value of the corresponding binary variable will be 1, otherwise it is left to 0. A target data can be the same as the source data when new fields are created to the existing data, otherwise a new data frame is created.
Example (ex3.3): The example shows the main commands and phases needed to create a binary coding for grouping a data.
