Using `Vector' in SPSS-x

<p>The VECTOR command, introduced with SPSS-X, is a powerful but I suspect little-used tool in our SPSS data manipulation kit. Essentially it is simply a means of grouping a set of variables together under one name which can then be referred to in subscripted form. This provides greatly increased flexibility in data transformations, frequently avoiding the need for bespoke external programs. The paper outlines the syntax of the command and illustrates some of the uses to which VECTOR can be put with four practical examples.
