Issue/Introduction
What does the error message 'Invalid object supplied as function' mean?
Environment
Product: TIBCO Spotfire S+
Version: All supported versions
OS: All supported operating systems
--------------------
Resolution
This error message states that Spotfire S+ has encountered something that looks like a function call but it cannot be interpreted correctly. The most common reason for this is due to the differences between writing equations longhand and coding them in the S+ language. For example, let's say that you want take 1/2 of (y-x)/x^2. In longhand you could write:
(1/2)((y-x)/x^2)
The convention that two equations enclosed in parentheses right next to each other is interpreted as multiplication. In the S+ language, this looks like you are trying to pass arguments to a function called 1/2. You need to implicitly state that they should be multiplied:
(1/2)*((y-x)/x^2)
(1/2)((y-x)/x^2)
