# Running create_lagged_df() is the next step in the forecastML forecasting
# process. If there are long gaps in data collection, like in this buoy dataset,
# and the user-supplied modeling algorithm cannot handle missing outcomes data,
# the best option is to filter these rows out in the user-supplied modeling function
# for train_model()
