Rolling Summary Statistics
rolling_stats(df, n_roll = NULL)
| df | a dataframe containing columns "x", "y", and "date |
|---|---|
| n_roll | numeric, number of fixes (e.g. width of the window) over which to
calculate rolling statistics. If NULL, the default is to roll over 3 hours for fix-rates
of 1 hour or less, and over 6 hours for fix rates occuring at intervals greater than 1 hour.
If your fix rate is every 4 hours or greater and n_roll is not set, the function
will warn you to set |
