| TimeDateSpecDates {fCalendar} | R Documentation |
A collection and description of functions for the
generation of sequences of dates according to
special date rules.
The functions for special 'timeDate' sequences are:
timeFirstDayInMonth | Computes the first day in a given month and year, |
timeLastDayInMonth | Computes the last day in a given month and year, |
timeFirstDayInQuarter | Computes the first day in a given quarter and year, |
timeLastDayInQuarter | Computes the last day in a given quarter and year, |
timeNdayOnOrAfter | Computes date that is a "on-or-after" n-day, |
timeNdayOnOrBefore | Computes date that is a "on-or-before" n-day, |
timeNthNdayInMonth | Computes n-th ocurrance of a n-day in year/month, |
timeLastNdayInMonth | Computes the last n-day in year/month. |
timeFirstDayInMonth(charvec, format = "%Y-%m-%d", zone = myFinCenter,
FinCenter = myFinCenter)
timeLastDayInMonth(charvec, format = "%Y-%m-%d", zone = myFinCenter,
FinCenter = myFinCenter)
timeFirstDayInQuarter(charvec, format = "%Y-%m-%d", zone = myFinCenter,
FinCenter = myFinCenter)
timeLastDayInQuarter(charvec, format = "%Y-%m-%d", zone = myFinCenter,
FinCenter = myFinCenter)
timeNdayOnOrAfter(charvec, nday = 1, format = "%Y-%m-%d",
zone = myFinCenter, FinCenter = myFinCenter)
timeNdayOnOrBefore(charvec, nday = 1, format = "%Y-%m-%d",
zone = myFinCenter, FinCenter = myFinCenter)
timeNthNdayInMonth(charvec, nday = 1, nth = 1, format = "%Y-%m-%d",
zone = myFinCenter, FinCenter = myFinCenter)
timeLastNdayInMonth(charvec, nday = 1, format = "%Y-%m-%d",
zone = myFinCenter, FinCenter = myFinCenter)
charvec |
a character vector of dates and times. |
FinCenter |
a character with the the location of the financial center named as "continent/city". |
format |
the format specification of the input character vector. |
nday |
an integer vector with entries ranging from
0 (Sunday) to 6 (Saturday).
|
nth |
an integer vector numbering the n-th occurence. |
zone |
the time zone or financial center where the data were recorded. |
We have implemented functions to generate special "timeDate"
sequences. These are functions to compute the last day in a given
month and year, to compute the dates in a month that is a n-day on or
after a given date, to compute the dates in a month that is a n-day
on or before a specified date, to compute the n-th ocurrances of a
n-day for a specified year/month vectors, and finally to compute
the last n-day for a specified year/month value or vector. n-days
are numbered from 0 to 6 where 0 correspond to the Sunday and 6 to
the Saturday.
timeLastDayInMonth
timeFirstDayInMonth
timeLastDayInQuarter
timeFirstDayInQuarter
timeNdayOnOrAfter
timeNdayOnOrBefore
timeNthNdayInMonth
timeLastNdayInMonth
these functions return timeDate objects on special dates. For
the functions timeLastDayInMonth and timeLastDayInMonth
return the last or first day respectively in a given month and year.
The same functionality for quarterly time horizons is returned by the
functions timeLastDayInQuarter and timeLastDayInQuarter.
Ror the function timeNdayOnOrAfter the date in the specified
month that is a n-day (e.g. Sun-day) on or after a given date, for
timeNdayOnOrBefore the date that is a n-day on or before a
given date, for timeNthNdayInMonth the nth ocurrance
of a n-day (nth = 1,...,5) in year, month, and
for {timeLastNdayInMonth} the last nday in year,
month will be returned as "timeDate" objects.
