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

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

#> [1] "2019-Q3" "2019-Q4" "2020-Q1" "2020-Q2"

# Set the day to the last day of the quarter

#> [1] "2019-Q1-90" "2019-Q2-91" "2019-Q3-92" "2019-Q4-92"

# Start the fiscal year in June
june <- 6L
y <- year_quarter_day(2019, 1:4, "last", start = june)

# Compare the year-month-day values that result from having different
# fiscal year start months
