Convert a weekday to an ordered factor

Source: R/weekday.R

weekday_factor() converts a weekday object to an ordered factor. This can be useful in combination with ggplot2, or for modeling.

weekday_factor(x, ..., labels = "en", abbreviate = TRUE, encoding = "western")

Arguments

x

[weekday]

A weekday vector.

...

These dots are for future extensions and must be empty.

labels

[clock_labels / character(1)]

Character representations of localized weekday names, month names, and AM/PM names. Either the language code as string (passed on to clock_labels_lookup()), or an object created by clock_labels().

abbreviate

[logical(1)]

If TRUE, the abbreviated weekday names from labels will be used.

If FALSE, the full weekday names from labels will be used.

encoding

[character(1)]

One of:

  • "western": Encode the weekdays as an ordered factor with levels from Sunday -> Saturday.

  • "iso": Encode the weekdays as an ordered factor with levels from Monday -> Sunday.

Value

An ordered factor representing the weekdays.

Examples

x <- weekday(1:7)

# Default to Sunday -> Saturday
weekday_factor(x)
#> [1] Sun Mon Tue Wed Thu Fri Sat
#> Levels: Sun < Mon < Tue < Wed < Thu < Fri < Sat

# ISO encoding is Monday -> Sunday
weekday_factor(x, encoding = "iso")
#> [1] Sun Mon Tue Wed Thu Fri Sat
#> Levels: Mon < Tue < Wed < Thu < Fri < Sat < Sun

# With full names
weekday_factor(x, abbreviate = FALSE)
#> [1] Sunday    Monday    Tuesday   Wednesday Thursday  Friday    Saturday 
#> 7 Levels: Sunday < Monday < Tuesday < Wednesday < Thursday < ... < Saturday

# Or a different language
weekday_factor(x, labels = "fr")
#> [1] dim. lun. mar. mer. jeu. ven. sam.
#> Levels: dim. < lun. < mar. < mer. < jeu. < ven. < sam.
