The command sets values defined by indexes in a given data field. The values are given in index-value pairs. If a field does not exist, then the parameters <len> and <type> must be given. The type is determined by one of the strings "int", "float" or "string". Note that a strong conversion is used meaning that, if an integer is given for a string field, then the value is handled as a string, and the same holds for all the other data types.
Example: In the following examples, the range (min/max) is computed to the data frame "minmax". The first field includes the minimum and the second field the maximum values, while the index 0 of the frame "minmax" refers to the first field in the source data "boston" (criminality). Thus, the operation setdata forces the minimum value for `criminality' to 5 and the maximum value to 50.
