Overlap calculation in R

overlap

overlap: The overlap package provides functions to calculate and visualize the overlap of two or more density distributions. The overlapEst function can be used to calculate the overlap of two density distributions, while the overlapPlot function can be used to visualize the overlap.

library(overlap)
library(ggplot2)

# Generate two random lists of numbers
set.seed(123)
list1 <- rnorm(100, mean = 5, sd = 1)
list2 <- rnorm(100, mean = 8, sd = 1)

# Calculate overlap density
overlapEst(list1, list2)

ggplot() + geom_density(aes(list1, fill = "list1"), alpha = .5) + 
  geom_density(aes(list2, fill = "list2"), alpha = .5) + theme_bw()

I personally believe that this result is more reliable.
