year-month-weekday-count-between {clock} | R Documentation |
This is a year-month-weekday method for the calendar_count_between()
generic. It counts the number of precision
units between start
and end
(i.e., the number of years or months).
## S3 method for class 'clock_year_month_weekday' calendar_count_between(start, end, precision, ..., n = 1L)
