Why is There a Tab in the Object Inspector Called Data (Nested)?

Some R-based outputs have a Data tab in the object inspector, but sometimes you may run across a Data (Nested) tab as well. This most commonly happens if an R-based table, such as a combined table, is nested under a visualization. The inputs and code for the underlying R-based table are in the Data (Nested) tab, whereas the Data tab has settings relevant to the visualization.

For example, you create a combined table and turn that into a visualization:

The settings for the visualization are in the Data tab in the object inspector:

And there are two additional sections that pop up: R Code - Data and Inputs Javascript - Data. These sections are the code that is creating the filtered input table and Data (Nested) tab. If you click Show Advanced Options below, the R Code and Inputs Javascript sections there are the code that is relevant to the visualization:

You will see the R Code - Data and Inputs Javascript - Data sections if you create a visualization using the object inspector directly from a custom R Calculation.
