Pretty breaks for date/times

Source: R/breaks.r

Uses default R break algorithm as implemented in pretty(). This is primarily useful for date/times, as extended_breaks() should do a slightly better job for numeric scales.

breaks_pretty(n = 5, ...)

Arguments

n

Desired number of breaks. You may get slightly more or fewer breaks that requested.
...

other arguments passed on to pretty()

Details

pretty_breaks() is retired; use breaks_pretty() instead.

Examples

one_month <- as.POSIXct(c("2020-05-01", "2020-06-01"))
demo_datetime(one_month)
#> scale_x_datetime()
demo_datetime(one_month, breaks = breaks_pretty(2))
#> scale_x_datetime(breaks = breaks_pretty(2))
demo_datetime(one_month, breaks = breaks_pretty(4))
#> scale_x_datetime(breaks = breaks_pretty(4))

# Tightly spaced date breaks often need custom labels too
demo_datetime(one_month, breaks = breaks_pretty(12))
#> scale_x_datetime(breaks = breaks_pretty(12))
demo_datetime(one_month,
  breaks = breaks_pretty(12),
  labels = label_date_short()
)
#> scale_x_datetime(breaks = breaks_pretty(12), labels = label_date_short())
