new timeDate method for $ for
extraction of components of timeDate objects
td, td$year,
td$month, and td$sec give numeric vectors
containing the corresponding components. In interactive sessions
completion is supported, usually by hitting the new timeDate methods for the base R functions
quarters and weekdays (they return character
vectors of names).
new timeDate method for months
returning a character vector. For now, a character vector will be
returned only if argument ‘abbreviate’ is set explicitly (to
TRUE or FALSE). If ‘abbreviate’ is missing,
the numeric values are returned, see the deprecation note below.
Deprecation Warning: a timeDate method for
months has existed for a long time but it was returning a
numeric vector, which is inconsistent with the other methods for months
in base R (they return names of months). Returning a numeric vector when
‘abbreviate’ is missing is a temporary compromise, to avoid breaking old
code but this should be considered deprecated. Use td$month
to get the numbers.
now timeDate(character(0)) returns a 0-length
“timeDate” object. Previously it was returning an NA
“timeDate” object of length 1 if argument ‘format’ was missing and a
0-length object otherwise.
changed the “timeDate” method for show to print
something like ‘timeDate of length 0’ along with the FinCenter, which
seems better than the previous output for this case.
new function InternationalWomensDay (suggested by
Alexander Bartel with code), fixes R-forge issue #6855). Now included in
the list returned by listHolidays.
new function earlyCloseNYSE gives datetimes of early
closings of NYSE, including scheduled and unscheduled ones. The
information is incomlete. This answers issue [#6757], see also the
related issue [#1356] mentioned below in the news for a previous
version.
all functions returning public and eclessiastical holidays get
new arguments value, na_drop, and
..., controlling the type of the return value and the
handling of missing values. Argument ... is for things like
‘format’ when applicable. Not all honour the new arguments though, see
below.
all functions returning public and eclessiastical holidays now
honour the new argument value.
some holiday functions were amended or rewritten to honour the
new argument na_drop. These include the England holidays
(‘GBxxx’), some Japan holidays (JPxxx), and a number of other functions
(e.g., `CAFamilyDay). Contributions and/or information needed to have
them do so is wellcome (e.g. dates when a holiday was introduced and/or
moved).
midnightStandard2() (and hence
timeDate()) was throwing a puzzling error when the input
character vector contained one or more NAs mixed with
non-NA’s.
whichFormat() was throwing error when the
first element of the input vector was NA. This
could be considered a feature but that’s inconsistent since
NAs at other positions were not causing trouble. Now
fixed.
the ‘character’ method for timeDate() was passing
only the first element of the input vector to
whichFormat(). This was preventing it from inferring the
format when argument ‘format’ was missing.
new function specialHolidayGB gives the special UK
one-off holidays for the requested years.
MilleniumDay is now deprecated, use
specialHolidayGB(1999).
fixed omissions in holidayLONDON and refactored it
completely. It became easier to maintain and orders of magnitude
faster.
fixed a bug in an internal function which was throwing errors
from holidayLONDON for some ranges including years before
1916.
GBEarlyMayBankHoliday,
GBSpringBankHoliday and GBSummerBankHoliday
now give dates according to historical rules, not simply according to
current ones. See the remarks above about the new arguments of holiday
functions.
major overhaul and update of the Japan’s holidays. Previously fixed dates were returned for each holiday. Now moving holidays are calculated (e.g., second month of January) and some exceptions handled (like holidays moved due to the Olympics in 2020 and 2021). Historical changes are (partially) taken into account. Further corrections and historical amendments are welcome.
Thanks to Sylvie Lachaud for reporting the issues with Japan holiday functions, as well as providing current correct definitions and extensive list of links.
new function JPMountainDay gives the relatively
recently introduced Japan holiday ‘Mountain Day’.
JPKeirouNoHi replaces JPKeirouNOhi. The
latter is an aberration from all other xxxNoHi Japanese
holiday functions and a source of difficult to spot errors. The old one
is now deprecated and will be removed in the future.
modified the ‘timeDate’ method for summary to return
an object from class “timeDate_summary” (rather than print directly) and
created a print method for the latter.
deprecated the timeDate method for cut,
see deprecation note for v4021.105 below.
stopped exporting all but one (.endpoints) functions
starting with a ‘.’. They all seem for internal purposes and/or have
similarly named functions with normal names.
removed .whichFormat and
.midnightStandard, not officially deprecated but had been
renamed to whichFormat() and
midnightStandard(), respectively, a long time ago.
removed several internal functions that are no longer used anywhere in the package.
removed file ‘namespace-tags.R’ as it had not been updated recently, see revision r83578 or earlier if you need it.
added the 2023 UK Bank holiday for the coronation of King Charles III.
axis.timeDate was not handling properly the case
when x was missing, leading to errors from R-devel check
(2023-01-07 r83578). Fix suggested by Uwe Lieges.
refactored file NAMESPACE to facilitate maintenance (that revealed the two omissions listed below).
CAFamilyDay (Canada Family Day) was missing from the
list returned by listHolidays(). It was missing only from
that list, holidayTSX() was including it when
applicable.
JPVernalEquinox was missing from the list returned
by listHolidays().
the financial centers are now updated to reflect changes in time
zones in recent years. The list returned by listFinCenter()
is synchronised with current time zone names. Previous names supported
by timeDate are available as aliases.
import selectively from ‘stats’ and ‘utils’.
London financial centre holidays - fixed and/or included
non-standard holidays (e.g., Early May Bank holiday was moved in 2020 to
VE day; Spring Bank holiday was moved in Queen’s Jubilee years; state
funeral of the Queen). Millenium day now is included in the result of
holidayLONDON(1999). The London holidays should now be
complete up to the time of writing this (1 Oct 2022).
renamed GBMayDay to
GBEarlyMayBankHoliday and GBBankHoliday to
GBSpringBankHoliday. The old names are somewhat ambiguous
and strongly discouraged but still available.
listHolidays() gives the new names.
the generic timeDate() gets argument ‘…’ to allow
methods for it to have additional arguments (e.g., for DST
gaps).
the ‘character’ method for timeDate() gets a new
argument dst_gap to control what to do with non-existent
DST times at the requested FinCenter with options to
add/subtract (“+”, “-”) the DST shift or set them to
NA.
timeDate() was not handling correctly some times
just after the switch to/from DST. This was visible mostly for time
zones away from GMT and GMT+1.
In timeSequence(), if any of the generated times
would fall in DST gaps, they are moved by “+1 hour”, corresponding to
dst_gap = "+" in timeDate. This is consistent
with seq for other time objects. Currently there is no
option to change this behaviour of timeSequence.
Previously timeSequence was moving DST gaps down by 1
hour (for by = ‘DSTday’ and similar). This was not consistent similar
time functions in R and was actually due to a bug (or unfinished DST
handling) in timeDate, see remarks for
timeDate above.
timeSequence() now throws error if argument
from is in a DST gap. It seems desirable to have a default
action for this case. Rolling the faulty time by an hour in the case of
‘DSTday’ may be suitable in most cases but for other values of
by it might be totally wrong.
updated the DST rules.
internally, refactored the way the DST rules are generated (not visible to users).
rulesFinCenter() now looks for a financial center
starting from the namespace of timeDate. Previously it was
starting from the environment of the caller which could result in using
an unrelated object or, if timeDate was loaded but not
attached, not finding it.
whichFormat() to accommodate a change in R-devel
after which as.character(Sys.time()) contains fractional
seconds. (format(Sys.time()) doesn’t; before this change in
R-devel both were dropping the fractional seconds). (fixed by Martin
Maechler, see timeDate rev 6286)the list returned by holidaysNYSE() was missing the
special closing days of the New York stock exchange (NYSE). Now it
should be complete (though there may be ommissions after 2011). This
fixes issue #1356 reported by Corwin Joy. Thanks to him and Ian E for
the insigthful discussion and useful links.
See also below. Contributions for the other exchanges and corrections are welcome.
holidaysNYSE() gets a new argument,
type, to select what type of the exchange’s closing days to
return. The default is to return all days in the requested years when
NYSE was closed for whatever reason. Use type = "standard"
and type = special to get the standard holidays and the
special closings, respectively.
Returning any closing day by default might be considered a breaking
change. However, not returning all closing days was perceived as
erroneous by users (eg issue #1356). In fact, the package itself
calculates business days by dropping weekends and days returned by
holidayXXXX.
Note that holiday() returns the actual dates of the
public holidays, while the corresponding days returned by
holidayXXXX are the resulting non-weekend closing days, if
any.
holidayTSX() now correctly calculates Christmas and
Boxing day closures when Christmas is on Monday. Fixes part (2) of issue
#1288 reported by Stefan Wilhelm (part (1) was fixed in a previous
release). The fix is really a patch for the specific issue, maybe the
same should be done when Christmas is on Sunday, for example.
Information/contribution on Canadian holidays is welcome.
now holiday() accepts also a function or a list of
functions for argument ‘Holiday’.
timeNthNdayInMonth could return a value in the
following month. Now fixed. This is bug #1463 reported with a fix by
Manny C. Note that the bug was not present for dates in the first day of
a month.
timeLastNdayInMonth could return a value in the
following month, e.g. ‘1996-06-04’ for the last Tuesday in May 1996. Now
fixed. The check of this function was prompted by the bug report for
#1463 (see above) for timeNthNdayInMonth but the error was
different.
the data.frame methods for kurtosis()
and skewness() now set attribute method as for
the other methods and as documented.
removed .holidayList() which had been replaced by
listHolidays() a long time ago and was not exported in
recent versions of timeDate.
updated documentation files.
timeDate method for cut has been
discouraged in the sources for a long time with a recommendation to use
window instead (just replace
cut(x, from = xx , to = yy) with
window(x, start = xx, end = yy). The cut
method will be deprecated in the next release and later removed or
replaced by a method that is consistent with the methods for
cut in base R.new maintainer: Georgi N. Boshnakov.
updated DESCRIPTION with links and moved all
Depends: to Imports:.
removed the line LazyData: yes from DESCRIPTION to
fix the NOTE on CRAN.
added the new US holiday, Juneteenth National Independence Day. Fixes #6755 by Ian E (ene100).
holidayTSX() now includes the Labour Day. Fixes part
(1) of issue #1288 reported by Stefan Wilhelm.
created a first version of _pkgdown.yml for more
organised view of the large number of objects in the package. Unpack the
tarball and run pkgdown::build_site() to build the site
locally. Don’t know if this could work directly off the R-forge
repository.
