Subset

Select menu: Data | Subset

Forms a vector containing a subset of the values from another vector. You can form a subset for either a variate, factor or text. The subset is defined by a logical condition, which is specified by the matching conditions where units with the value TRUE (neither zero nor missing value) for the condition are included in the subset, others are omitted.

After you have imported your data, from the menu select Data | Subset.

Available data

This lists variates, factors and texts which are available to form a subset from. Double-click a name to copy it to the current input field or type the name.

Data to subset

Specify the name of the data that you want to create a subset from. You can either type the name in directly or double-click a name from the Available data list.

Name of subset

Specify the name for the new subset of data. You can either type the name in directly or double-click a name from the Available data list. Note: If a name is copied from the Available data list it will be overwritten.

Matching condition

Enter the logical condition that you want to use to subset your data. You can use either just the first field or both fields to specify the logical condition. If you use both fields the two logical conditions are combined using either And or Or.

Comparisons

This lists the available comparisons that can be used to create the subset. Double-click the name of the comparison that you want to use to insert the comparison operator symbol into the matching condition.
