Selection Helper Functions for the Portalcasting App

Construct vectors of available choices and make selections, with respect to species, dataset, model, and moons.

Usage

  global = global_list(),
  event = "initial_evaluation_tab",
  rv = NULL
)

selected_newmoonnumber(
  global = global_list(),

  rv = NULL
)

available_historic_end_newmoonnumbers(
  global = global_list(),
  event = "initial_forecast_tab",
  rv = NULL
)

selected_historic_end_newmoonnumber(
  global = global_list(),
  event = "initial_forecast_tab",
  rv = NULL
)

available_species(
  global = global_list(),
  event = "initial_forecast_tab",
  rv = NULL
)

selected_species(
  global = global_list(),
  event = "initial_forecast_tab",
  rv = NULL
)

available_datasets(
  global = global_list(),
  event = "initial_forecast_tab",
  rv = NULL
)

selected_dataset(
  global = global_list(),
  event = "initial_forecast_tab",
