week_breaks {phylepic}

Breaks for week-binning date axes

Description

Breaks for week-binning date axes

Usage

week_breaks(width = 1L, week_start = getOption("phylepic.week_start"))

Arguments

width

Number of weeks between breaks (e.g. 2 will give a break every fortnight).

week_start

Day the week begins (defaults to Monday). Can be specified as a case-insensitive English weekday name such as "Monday" or an integer. Since you generally won't want to mix definitions, it is more convenient to control this globally with the "phylepic.week_start" option, e.g. options(phylepic.week_start = "Monday").

Value

A break function suitable for use in ggplot2::scale_x_date() et al.
