Which of the following features allows users to create scripts that can perform a calculation...

 Data functions are scripts that can perform any type of calculation and return the results to an analysis. They can be created using R, Python, or other languages, and they can take input from data tables, columns, or properties, and output data tables, columns, or properties. Data functions can be executed on demand, automatically, or triggered by markings or filters. Data functions can be added to an analysis using the Tools > Register Data Functions menu option in the Spotfire Analyst client, or using the Add Data Function option in the Spotfire Server web interface. References: What are data functions?, Spotfire Data Function Library: Python and R Scripts for Data Analysis, Linear Regression in R | A Step-by-Step Guide & Examples
