Convenience functions for dealing with financial years

From grattan v1.7.1.4, these are reexports from the fy-package.

Arguments

yr_ending	An integer representing a year.
fy.yr	A string suspected to be a financial year.
date	A string or date for which the financial year is desired. Note that yr2fy does not check its argument is an integer.
assume1901_2100	For yr2fy, assume that yr_ending is between 1901 and 2100, for performance. By default, set to getOption("grattan.assume1901_2100", TRUE).

Value

For is.fy, a logical, whether its argument is a financial year. The following forms are allowed: 2012-13, 201213, 2012 13, only. For fy.year, yr2fy, and date2fy, the financial year. For the inverses, a numeric corresponding to the year.

fy.year is a deprecated alias for yr2fy, the latter is slightly more efficient, as well as more declarative.

fy2yr converts a financial year to the year ending: fy2yr("2016-17") returns 2017. yr2fy is the inverse: yr2fy(fy2yr("2016-17")) == "2016-17".

fy2date converts a financial year to the 30 June of the financial year ending.

date2fy converts a date to the corresponding financial year.

Details

The following forms are permitted: 2012-13, 201213, 2012 13, only. However, the 2012-13 form is preferred and will improve performance.

Examples

is.fy("2012-13")
#> [1] TRUE
is.fy("2012-14")
#> [1] FALSE
yr2fy(2012)
#> [1] "2011-12"
fy2yr("2015-16")
#> [1] 2016
date2fy("2014-08-09")
#> [1] "2014-15"
