Examples

# Within shiny both session and input variables will exist,
# this creates examples here for testing purposes:
sess_res = MB_test_mksession()
session = sess_res$session
input   = sess_res$input

# Configuration files
FM_yaml_file  = system.file(package = "formods", "templates", "formods.yaml")
MOD_yaml_file = system.file(package = "ruminate", "templates", "MB.yaml")

# Creating an empty state object
state = MB_fetch_state(id              = "MB",
                       id_ASM          = "ASM",
                       input           = input,
                       session         = session,
                       FM_yaml_file    = FM_yaml_file,
                       MOD_yaml_file   = MOD_yaml_file,
                       react_state     = NULL)
