List Operator (FPScript)
Combines any values into a list.
Syntax
[ [<ElementName1>] Expression1 [[, [<ElementName2>] Expression2], ...] ]
The syntax of the list operator consists of the following elements:
Element |
Description |
|---|---|
Expression1...n |
Any expressions for which the results can be combined into a list. |
ElementName1...n |
An optional name for the list element. |
Remarks
All data structures and data types are allowed for the elements in lists. Especially a list element can in turn be a list itself. Therefore, hierarchical data structures can be constructed as lists.
As an option, you can assign a name to each list element that you can then use to access the element.
The first element of a list is called the primary element and should contain the most important data. Most FPScript functions only process the primary element when a list is passed as an argument.
Notes:
If you want to create a list for which the first element is also a list, then for syntactical reasons you must make sure to insert at least one empty space between the two '[' characters; for instance, [ [1, 2], 3, 4] and not [[1, 2], 3, 4].
Use the List FPScript function when you want to determine the name of the list element at runtime, such as when taken from variables.

Examples
[ SolutionVector, ConfidenceInterval ] |
Combines the results of a regression stored in the variables SolutionVector and ConfidenceInterval for a list. |
[ <Solution>SolutionVector, <Confidence>ConfidenceInterval ] |
In this case, the list elements are called "Solution" and "Confidence". |
