Thinned discrete breaks that keep the end values

Source: R/ggplot-layers.R
calendar_breaks.Rd

A breaks function for discrete timeslice axes: picks about n evenly spaced labels and ALWAYS includes the first and last – dense vocabularies (d001..d365, h00..h23) stop overlapping without losing the axis range. Pass it to ggplot2::scale_x_discrete() / scale_y_discrete():

Usage

calendar_breaks(n = 6)

Arguments

n

Approximate number of labels (>= 2; default 6).

Value

A function of the level vector, for breaks =.
