| bin | Code classes in a classified data into binary variables |
| -c <cldata> | classified data for identifying records |
| -d <data> | source data |
| -dout <trgdata> | result data |
| [-pre <prefix>] | prefix for fields to be created |
This command encodes a given classified data related to a source data. For each class a new binary (integer) field is created. Then, the index of each data record is matched to the indexes in the class. If the index is found, the value of the binary variable corresponding to that class will be `1', otherwise `0'. Target data can be the same as source data. In that case, new fields are created to the existing data frame. Otherwise, a new data frame is created. If <prefix> is specified, created fields are named as prefix_n, otherwise the names of the classes of <cldata> are used.
Example (ex3.3): This example shows necessary commands and phases needed to create a binary coding for a grouping of data.
