Calculate bin width for a histogram using various recommended methods

Description

There are many different methods that have been recommended over the years to determine an appropriate bin width for a histogram. This function collects those methods so that they are available easily. No one is really recommended over another. A few should be considered and then choose the best to visualize the distribution.

Usage

calc_bin_width(x, binw_select = "FD")

Arguments

x	A numeric object
binw_select	Character choice for which method to use to calculate bin width: "FD" (Default), "Sturges", "Scott", "Square-root", "Rice", "Shimazaki", "Juran"

Value

A numeric

library(ggplot2)

calc_bin_width(diamonds$carat, binw_select = "FD")

ggplot(data = diamonds,
       aes(x = carat)) +
  geom_histogram(colour = "white",
                 binwidth = calc_bin_width(diamonds$carat, binw_select = "FD"))
