R: Grouping: year-day

year-day-group {clock} | R Documentation

## Grouping: year-day

### Description

This is a year-day method for the `calendar_group()` generic.

Grouping for a year-day object can be done at any precision, as long as `x` is at least as precise as `precision`.

### Usage

    ## S3 method for class 'clock_year_day'
    calendar_group(x, precision, ..., n = 1L)

### Arguments

`x` | `[clock_year_day]` A year-day vector.
`precision` | `[character(1)]` One of: `"year"` `"day"` `"hour"` `"minute"` `"second"` `"millisecond"` `"microsecond"` `"nanosecond"`
`...` | These dots are for future extensions and must be empty.
`n` | `[positive integer(1)]` A single positive integer specifying a multiple of `precision` to use.

### Value

`x` grouped at the specified `precision`.

### Examples

    x <- seq(as_naive_time(year_month_day(2019, 1, 1)), by = 5, length.out = 20)
    x <- as_year_day(x)
    x

    # Group by day of the current year
    calendar_group(x, "day", n = 20)
