Adjust a vector of dates following a business-day convention
adjust_cpp(dates, bdc = 0L) adjust(dates, bdc = c("Following", "ModifiedFollowing", "Preceding", "ModifiedPreceding", "Unadjusted", "HalfMonthModifiedFollowing", "Nearest"))adjust_cpp(dates, bdc = 0L) adjust(dates, bdc = c("Following", "ModifiedFollowing", "Preceding", "ModifiedPreceding", "Unadjusted", "HalfMonthModifiedFollowing", "Nearest"))
dates |
A Date vector with dates |
bdc |
A character variable describing one of several supported values, the C++ version implements expects a corresponding integer value |
This function takes a vector of dates and returns another vector of dates of the same length returning at each position the adjusted date according to the selected business-day convention. Currently supported values for the business day convention are (starting from zero): ‘Following’, ‘ModifiedFollowing’, ‘Preceding’, ‘ModifiedPreceding’, ‘Unadjusted’, ‘HalfModifiedFollowing’ and ‘Nearest’.

adjust(Sys.Date()+0:6)adjust(Sys.Date()+0:6)
Advance a date to the next business day plus an optional shift
advanceDate(rd, days = 0L)advanceDate(rd, days = 0L)
rd |
A Date object describing the date to be advanced to the next business day. |
days |
An optional integer offset applied to the date |
This function takes a given date and advances it to the next business day under the current (global) calendar setting. If an optional offset value is given it is applied as well.
The advanced date is returned
advanceDate(Sys.Date(), 2) # today to the next biz day, plus 2 daysadvanceDate(Sys.Date(), 2) # today to the next biz day, plus 2 days
Advance a vector of dates by a given number of time units
advanceUnits_cpp(dates, n, unit, bdc, emr) advanceUnits(dates, n, unit = c("Days", "Weeks", "Months", "Years", "Hours", "Minutes", "Seconds", "Milliseconds", "Microseconds"), bdc = c("Following", "ModifiedFollowing", "Preceding", "ModifiedPreceding", "Unadjusted", "HalfMonthModifiedFollowing", "Nearest"), emr = FALSE)advanceUnits_cpp(dates, n, unit, bdc, emr) advanceUnits(dates, n, unit = c("Days", "Weeks", "Months", "Years", "Hours", "Minutes", "Seconds", "Milliseconds", "Microseconds"), bdc = c("Following", "ModifiedFollowing", "Preceding", "ModifiedPreceding", "Unadjusted", "HalfMonthModifiedFollowing", "Nearest"), emr = FALSE)
dates |
A Date vector with dates |
n |
An integer variable with the number of units to advance |
unit |
A character variable describing one of several supported values; the C++ version implements expects a corresponding integer value |
bdc |
A character variable describing one of several supported values, the C++ version implements expects a corresponding integer value |
emr |
A boolean variable select end-of-month, default is ‘FALSE’ |
This function takes a vector of dates and returns another vector of dates of the same length returning at each position the date advanced by the given number of steps in the selected time unit, also respecting a business day convention and and of month boolean switch. Currently supported values for the time unit are ‘Days’, ‘Weeks’, ‘Months’ ‘Years’, ‘Hours’, ‘Seconds’, ‘Milliseconds’ and ‘Microseconds’; all are specified as integers. Note that intra-daily units are not currently supported for advancing ‘Date’ objects. Currently supported values for the business day convention are (starting from zero): ‘Following’, ‘ModifiedFollowing’, ‘Preceding’, ‘ModifiedPreceding’, ‘Unadjusted’, ‘HalfModifiedFollowing’ and ‘Nearest’.

A Date vector with interval start dates |
to |
A Date vector with interval end dates |
includeFirst |
A boolean indicating if the start date is included, default is ‘TRUE’ |

A boolean indicating if the end date is included, default is ‘FALSE’ |
This function takes two vectors of start and end dates and returns another vector of the number of business days between each corresponding date pair according to the active calendar.
A numeric vector with the number of business dates between the corresponding date pair
