New holiday and calendar API and corresponding vignette
vignette("holidays-calendars") (#96):
rholiday() creates a new holiday from a holiday name
and a rschedule that defines when the holiday occurs. There are a number
of pre-created holidays prefixed with hol_*(), such as
hol_christmas() and hol_us_thanksgiving().
Holidays are rschedules, so you can use all of the alma_*()
functions on them.
hol_observe(), hol_offset(), and
hol_rename() are three helpers for the holiday API. In
particular, hol_observe() tweaks a holiday’s observance
date to align with when your business actually celebrated that
holiday.
rcalendar() bundles multiple holidays together into
a calendar. Calendars are similar to runion()s, so you can
use all the alma_*() functions on these, but they also come
with their own specialized API of functions that start with
cal_*(), such as cal_match() to look up the
holiday name a date corresponds to, and cal_events() to
filter for all of the holidays within a particular year.
cal_us_federal() is an example calendar representing
the federal holidays recognized in the United States.
New roffset() for creating an rschedule with events
that are offset from an existing rschedule (#94).
New rcustom() for creating an rschedule from
manually defined event dates (#90).
alma_events() has gained a year
argument to limit the returned set of events to specific years.
runion(), rintersect(), and
rsetdiff() have all gained ... which allows
you to provide rschedules at creation time. This is now the preferred
way to create these set-based rschedules (#91).
Steppers created with stepper() now work as
.before and .after arguments of
slider::slide_index() and friends (#80).
The following functions have been deprecated in favor of more intuitively named alternatives (#83):
recur_on_mday() ->
recur_on_day_of_month()recur_on_wday() ->
recur_on_day_of_week()recur_on_yday() ->
recur_on_day_of_year()recur_on_yweek() ->
recur_on_week_of_year()recur_on_ymonth() ->
recur_on_month_of_year()These functions are being aggressively deprecated and will be removed in the next minor version of almanac.
The family of add_*() functions has been deprecated
(#92).
add_rschedule() has been deprecated in favor of
using the ... argument of runion(),
rintersect(), and rsetdiff()
directly.
add_rdates() has been deprecated in favor of using a
combination of runion() and
rcustom().
add_exdates() has been deprecated in favor of using
a combination of rsetdiff() and
rcustom().
These functions are being aggressively deprecated and will be removed in the next minor version of almanac.
The offset argument of
recur_on_easter() is deprecated in favor of using
roffset() (#94).
All almanac class names are now prefixed with
almanac_* to avoid potential clashes with other
packages.
The recur_with_week_start() argument
wday has been renamed to day.
The following developer facing functions have been removed because they are either no longer applicable or provided extension mechanisms that are not very useful in practice (#93):
new_rbundle()new_runion()new_rintersect()new_rsetdiff()rbundle_restore()recur_for_count() no longer overrides
until (#95).
New almanac_since() and almanac_until()
helpers to access the default since and until
values used for all rules (#95).
Greatly improved the print methods of all almanac classes using cli (#86).
Updated internal JavaScript rrule library to version 2.7.2 (#82).
R >=3.5.0 is now required, which is in line with tidyverse standards.
Explicitly imports R6::R6Class() and
V8::v8() to avoid R CMD Check false alarms (#74).
Fix USBAN error of casting NA_real_ and
NaN to integer (#72).
