Correcting Histogram Density Calculation in R with ggplot2
Step 1: Identify the issue with the original code The original code uses ..count../sum(..count..) in the aes function of geom_histogram, which is incorrect because it divides the count by the sum of counts, resulting in values that do not add up to 1. Step 2: Determine the correct method for calculating density To calculate the density, we need to divide the count by the binwidth. The correct method is (..density..)*binwidth.
