How to Create a Binary Filter from Selected Data

There are many ways to create a filter in Displayr, and some involve transforming the Structure of the data. The Filters from Selected Data automation will automatically create new filter variables for each category in the data you have selected. You will need to do this in a few circumstances, such as when:

You want a filter variable for each category in a categorical (Nominal) variable.
You want merged categories and NETs created on a Summary table to become a filter variable.

This article has the steps required to create an individual filter for each answer code shown below...

The first table is a Nominal variable, and the second table is a copy with categories merged and netted. After running the automation, these will appear in the Data Sources tree as individual Binary - Multi: Non-mutually exclusive categories variables usable in the Filter(s) dropdown on outputs and Filter header on Pages in View Mode.
