year_quarter_day() constructs a calendar from the fiscal year, fiscal quarter, and day of the quarter, along with a value determining which month the fiscal year starts in.

year_quarter_day(
  year,
  quarter = NULL,
  day = NULL,
  hour = NULL,
  minute = NULL,
  second = NULL,
  subsecond = NULL,
  ...,
  start = NULL,
  subsecond_precision = NULL
)

Arguments

year

[integer]

The fiscal year. Values [-32767, 32767] are generally allowed.

quarter

[integer / NULL]

The fiscal quarter. Values [1, 4] are allowed.

day

[integer / "last" / NULL]

The day of the quarter. Values [1, 92] are allowed.

If "last", the last day of the quarter is returned.

hour

[integer / NULL]

The hour. Values [0, 23] are allowed.

minute

[integer / NULL]

The minute. Values [0, 59] are allowed.

second

[integer / NULL]

The second. Values [0, 59] are allowed.

subsecond

[integer / NULL]

The subsecond. If specified, subsecond_precision must also be specified to determine how to interpret the subsecond.

If using milliseconds, values [0, 999] are allowed.

If using microseconds, values [0, 999999] are allowed.

If using nanoseconds, values [0, 999999999] are allowed.

...

These dots are for future extensions and must be empty.

start

[integer(1) / NULL]

The month to start the fiscal year in. 1 = January and 12 = December.

If NULL, a start of January will be used.

subsecond_precision

[character(1) / NULL]

The precision to interpret subsecond as. One of: "millisecond", "microsecond", or "nanosecond".

Value

A year-quarter-day calendar vector.

Details

Fields are recycled against each other.

Fields are collected in order until the first NULL field is located. No fields after the first NULL field are used.
