get_boundary {busdater}R Documentation

Get date's business period boundary.


The get_boundary will shift the input date vector by a number of months and years i.e. date + offset_period * offset_type. It will handle the typical business date arithmetic.


get_boundary(date = Sys.Date(), offset_period = 0,
  offset_type = "year", bus_period = "FY", boundary = "1st day",
  opt_fy_start = getOption("busdaterFYstart", default = "07-01"))



A date vector for which financial year is required. Date must be POSIXct or POSIXlt or Date objects.


A positive or negative number coercible to integer to shift the year by, e.g. in the case of get_fy, -1 for previous year, 1 for next year. More generally in page_boundaries function it is a number of periods of a specified period type


It is either "month" or "year"


It is either "get_fy" for financial year, "CE" for calendar year or "M" for month


Either "1st day" for the first day of the period or "last day" for the end of the period.


A string in the format of "MM-DD" representing the start of financial year, e.g. "01-01" for 1st of January or "07-01" for 1st of July. This package caters for financial years that have a fixed start date. It does not cater for moving dates e.g. last Friday of September.


A vector of dates.
