Details on Expression Functions


Use the Expression Functions dialog to register a function in the Spotfire expression language that is based on TIBCO Enterprise Runtime for R. Once an expression function has been created, it is automatically available in the Spotfire expression language.

Note: If you are developing scripts using TIBCO Enterprise Runtime for R, we recommend that you use RStudio, a full-featured, open-source integrated development environment for working with R code. It is provided independently of TIBCO Software Inc. You can configure RStudio to use the TIBCO Enterprise Runtime for R engine and to display its language reference. Also, you can access the TIBCO Enterprise Runtime for R language reference at https://docs.tibco.com/products/tibco-enterprise-runtime-for-r.

  1. Select Edit > Data Function Properties (G), and then click the Expression Functions tab.

  2. Click New.
