R is a popular open-source environment for statistical analysis. Tableau Desktop can now connect to R through calculated fields and take advantage of R functions, libraries, and packages, and even the saved models. These calculations dynamically invoke the R engine and pass values to R via the Reserve package and they are returned to Tableau.
Tableau Server can be configured to connect to an instance of Rserve through the tabadmin utility, allowing anyone to view a dashboard containing the R functionality.
Combining R with Tableau gives us the ability to bring deep statistical analysis into drag-and-drop visual analytics.
