Method to save expanded data — save_expanded

This method is used internally by expand_trials to save the data to the "datastore" defined in set_expansion_options.

Usage

save_expanded_data(object, data)

# S4 method for class 'te_datastore_datatable'
save_expanded_data(object, data)

Arguments

object: An object of class te_datastore or a child class.
data: A data frame containing the expanded trial data. The columns trial_period and id are present, which may be used in methods to save the data in an optimal way, such as with indexes, keys or separate files.

Value

An updated object with the data stored. Notably object@N should be increased

Examples

temp_dir <- tempfile("csv_dir_")
dir.create(temp_dir)
datastore <- save_to_csv(temp_dir)
data(vignette_switch_data)
save_expanded_data(datastore, vignette_switch_data[1:200, ])
