The isSuffix function checks whether a string is a suffix or not, and returns True in the rows of the column ending with the string value; otherwise False is returned.
isSuffix(column, value, binary)
If you are using continuous attributes, check the Flow Execution Parameters.
The nominal attribute in which the value will be checked. If it is not nominal, it will be casted to nominal upon function’s computation. The column parameter is mandatory.
The value to be checked in the column. If it is not nominal, it will be casted to nominal upon function’s computation. The value parameter is mandatory.
If it is True, or not specified, results will be provided as Booleans (True/False), while if it is False, results will be provided in binary form (1/0).
The following example uses the Adult dataset.
In this example, we want to know if the string ‘gov’ is a suffix for all the values of the occupation attribute.
Add a new attribute, which we have called suffix, and type the following formula:
As we have specified the binary parameter as False, the results will be provided in binary form (1/0), where 1 means True, and 0 False.
