Examples

# Initialize agd_worker R6 class
agd_data <- agd_worker$new(
  id = "jane-canuck",
  age = 10,
  agd_lfe = system.file("extdata", "jane-canuck-lfe.agd", package = "chms"),
  agd_nml = system.file("extdata", "jane-canuck-nml.agd", package = "chms"),
  epoch_length = 15,
  day_max = 3,
  sleep_algo = "barreira",
  non_wear_algo = "barreira"
)

# Load data
agd_data$load()

# Clean data
clean_agd_data(agd_data)

# Store updated data
dt <- agd_data$data$clean
