The period is parsed into frequency and period and returned as a named list.
parse_period(period)A character specification used for time-based grouping. The
general format to use is "frequency period" where frequency is a number
like 1 or 2, and period is an interval like weekly or yearly. There must be
a space between the two.
Note that you can pass the specification in a flexible way:
1 Year: '1 year' / '1 Y'
This shorthand is available for year, quarter, month, day, hour, minute, second, millisecond and microsecond periodicities.
Additionally, you have the option of passing in a vector of dates to use as custom and more flexible boundaries.
