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 Liege.
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.
