breaks_extended: Automatic breaks for numeric axes

In r-lib/scales: Scale Functions for Visualization

Automatic breaks for numeric axes

Description

Uses Wilkinson's extended breaks algorithm as implemented in the labeling package.

Usage

breaks_extended(n = 5, ...)

Arguments

n	Desired number of breaks. You may get slightly more or fewer breaks that requested.
...	other arguments passed on to labeling::extended()

Value

All breaks_() functions return a function for generating breaks. These functions takes, as their first argument a vector of values that represent the data range to provide breaks for. Some will optionally take a second argument that allows you to specify the number of breaks to recieve.
