Example 6: Density & Histogram in Same ggplot2 Plot. We can also overlay our histogram with a probability density plot. For this task, we need to specify y = ..density.. within the aesthetics of the geom_histogram function and we also need to add another line of code to our ggplot2 syntax, which is drawing the density plot:

The Histogram in R Programming is very useful to visualize the statistical information that organized in user-specified bins (range, or breaks). Though it looks like … You can plot a histogram in R with the hist function.
