Introduction

prettybreaks contains functions to create pretty breaks for numeric vectors.

Its main function pretty2() is similar to base::pretty() but allows to use different number systems and other tweaks, see examples below.

The algorithm is based on [1].

Examples

library(prettybreaks)

x <- 1:100

pretty2(x)                        

pretty2(x, n = 4)                 

pretty2(x, base = 5)              

pretty2(x, p = c(10/7, 20/7, 50/7))
