Easily combine modules and parameters to form a model ensemble

Usage

combineasy(model_templates, modules = NULL, parameters = NULL)

Arguments

model_templates

(list(DiseasyModel))
Provide a list of model templates that will be initialized with (functional) modules and parameters.

modules

(tibble)
The combination of modules to load into the model instances (generated by tidyr::expand_grid).

parameters

(tibble)
The combination of parameters to set in the model instances (generated by tidyr::expand_grid).

Value

A list of model instances with the class DiseasyEnsemble.

Examples

  # Create a small ensemble with the `DiseasyModelG1` model template
  observables <- DiseasyObservables$new(
    diseasystore = DiseasystoreSeirExample,
    conn = DBI::dbConnect(duckdb::duckdb())
  )

  ensemble <- combineasy(
    model_templates = list(DiseasyModelG1),
    modules = tidyr::expand_grid(
      observables = list(observables)
    )
  )

  print(ensemble)
#> DiseasyEnsemble: DiseasyModelG1 (hash: bec5f) 

  summary(ensemble)
#> DiseasyEnsemble consisting of:
#> DiseasyModelG1: 1 

  rm(observables)
