Specification

Alias: none

Argument(s): STRING

Default: use of last variables parsed

Description

The optional id_variables keyword accepts a string that uniquely identifies this variables block. A model can then use these variables by specifying the same string in its variables_pointer specification.

Default Behavior

If the id_variables specification is omitted, a particular variables specification will be used by a model only if that model does not include an variables_pointer and the variables block was the last (or only) one parsed.

Usage Tips

  • It is a best practice to always use explicit variables IDs and pointers to avoid confusion.
  • If only one variables block exists, then id_variables can be safely omitted from the variables block (and variables_pointer omitted from the model specification(s)), since there is no ambiguity.

Examples

For example, a model specification including

model
  variables_pointer = 'V1'

will link to a response set with

  id_variables = 'V1'
