We can use mlts_transform to convert the data into a machine learning-friendly format with a 7-day lag:
mlts <- mlts_transform(
r_enwiki, date, pageviews,
p = 7, # how many previous points of data to use as features
granularity = "day", # optional, can be automatically detected,
extras = TRUE, extrasAsFactors = TRUE # FALSE by default :D
)
head(mlts)| dt | y | mlts_extras_monthday | mlts_extras_weekday | mlts_extras_week | mlts_extras_month | mlts_extras_year | mlts_lag_1 | mlts_lag_2 | mlts_lag_3 | mlts_lag_4 | mlts_lag_5 | mlts_lag_6 | mlts_lag_7 |
