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"))

Arguments

date	A date vector for which financial year is required. Date must be POSIXct or POSIXlt or Date objects.
offset_period	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
offset_type	It is either "month" or "year"
bus_period	It is either "get_fy" for financial year, "CE" for calendar year or "M" for month
boundary	Either "1st day" for the first day of the period or "last day" for the end of the period.
opt_fy_start	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.

Value

A vector of dates.

Examples

# the 1st day of the current financial year
get_boundary()
#> [1] "2018-07-01"

# the last day of the current financial year
get_boundary(boundary = "last day")
#> [1] "2019-06-30"

# the last day of the last calendar year
get_boundary(offset_period = -1, bus_period = "CY", boundary = "last day")
#> [1] "2018-12-31"

# the last day of month 14 months from now
get_boundary(offset_period = 14, offset_type = "month",
                  bus_period = "M", boundary = "last day")
#> [1] "2020-03-31"

# The first day of financial years for dates 3 months before the given dates
