How to Control Which Calculations are Filtered in View Mode

When viewing a published document in View mode and applying a filter to the Page, the expected behavior is for all outputs on that Page to filter. This is not always the case with Calculations using R Code. This post describes the steps required to ensure Calculations using R Code are also filtered. The posts also contain steps to take if you wish to exclude the Calculations from filtering in View mode.

Requirements

A Calculation using R Code.
A binary variable that can be used as a filter.
A published Displayr document.

Method - Adding a Filter to an R Output

In Edit mode, select the Calculation using R code you wish to filter in View mode.
In Properties > Data > R Code > Edit Code, add "[QFilter]" to the part of the code referencing the data source (e.g. variable or table) inside the Code panel.
Click Calculate.
Go to Share > Publish to web or Republish.

Method - Removing the Filter from Automatically Created R Output

Many analyses created in Displayr are based on R calculations, with the R code already referencing the "[QFilter]". To remove it, follow the steps outlined below.

Select the automatically created Calculation using R code and go to Properties > Data > R Code > Edit Code.
In the Code panel, find all mentions of QFilter and replace them with TRUE.
Click Calculate.
Go to Share > Publish to web or Republish.

Method - Uncheck 'Calculate automatically'

Another approach to ensure that the Calculation using R code doesn't change based on the selected filter in view mode is to disable the Calculate automatically feature. By doing this the Calculation will remain static in View mode.

Select the automatically created Calculation using R code and go to the object inspector.
Untick the Calculate Automatically box to the right of the Calculate button in Properties .
Go to Share > Publish to web or Republish.
