calendar_month_factor: Convert a calendar to an ordered factor of month names
Description
calendar_month_factor() extracts the month values from a calendar and
converts them to an ordered factor of month names. This can be useful in
combination with ggplot2, or for modeling.
This function is only relevant for calendar types that use a month field,
i.e. year_month_day() and year_month_weekday(). The calendar type must
have at least month precision.
These dots are for future extensions and must be empty.
labels
[clock_labels / character(1)]
Character representations of localized weekday names, month names, and
AM/PM names. Either the language code as string (passed on to
clock_labels_lookup()), or an object created by clock_labels().
abbreviate
[logical(1)]
If TRUE, the abbreviated month names from labels will be used.
If FALSE, the full month names from labels will be used.
