id parameter in R simmer package

There are several functions in the R simmer package that have the argument id = 0. Usually the functions are associated with selecting a certain resource (e.g. seize_selected). I haven't been able to find any documentation on what this parameter does other than selection identifier for nested usage. Does anyone know what this means or have a use case for setting this to something other than its default value of 0?

I'm trying to see if it will help me select a coupled resource. For example, if I select "Bar1" resource, then I have to select "Server1" as a related resource. The wording of the reference makes me think this might help, but I'm not sure.

Yes, that's exactly what it is for. If you select a second resource, you lose your previous selection... unless you give it a different id. So, in your case:

  ... %>%
  select("Bar1", id=0) %>%
  ...
  select("Server1", id=1) %>%
  ...

and then you can use those ids in other activities to refer to those selections.
