power_breaks: Axis Breaks for power transformations

In FelixTheStudent/ggpower: Package for power transformations, useful e.g. in ggplot

Description

Return vector of breaks that span the lims range evenly _after_ transformation

Usage

power_breaks(lims, power, n_breaks = NULL)

Arguments

lims	The range for which breaks should be produced.
power	PARAM_DESCRIPTION
n_breaks	deprecated, does not influence the result. Stop using altogether.

Details

The breaks will be numbers that are powers of 2. The base of 2 was chosen for three reasons. Firstly, the resulting breaks are sufficiently dense (example: in the [1,100]-interval, 2^x produces 2, 4, 8, 16, 32 and 64, while 10^x only produces 1, 10 and 100, which is often rather sparse). Secondly, for x>1 the powers of 2 are all integers (in contrast to 1.2^x, etc.). And thirdly, 2^x are numbers familiar to many people, especially geeks and scientists.
