Examples

# YAML configuration files from the package:
FM_yaml_file  = system.file(package = "formods", "templates", "formods.yaml")
MOD_yaml_file = system.file(package = "formods", "templates", "UD.yaml")
# This is the module id:
id = "UD"
# Within shiny both session and input variables will exist,
# this creates examples here for testing purposes:
sess_res = UD_test_mksession(session=list())
session = sess_res$session
input   = sess_res$input
state = UD_fetch_state(
           id            = id,
           input         = input,
           session       = session,
           FM_yaml_file  = FM_yaml_file,
           MOD_yaml_file = MOD_yaml_file )
  
 ds_res = UD_fetch_ds(state)
