com.mockturtlesolutions.snifflib.stats.Sort

public class Sort
extends java.lang.Object

Sorts rows of a DataSet with respect to one or more variables in the DataSet. If multiple variables are used to sort, the sorting is done in the sequence in which those variables are entered into the "by-variables". If response variables are supplied then only those variables are sorted and returned in the result.
