WebJun 3, 2016 · The bin-width is set to h = 2 × IQR × n − 1 / 3. So the number of bins is ( max − min) / h, where n is the number of observations, max is the maximum value and min is the minimum value. In base R, you can use: hist (x, breaks="FD") For other plotting libraries without this option (e.g., ggplot2 ), you can calculate binwidth as: WebThe Optimal Binning Algorithm.
