NettetOne solution could be to create faceted histograms, plotting one per group in a row or column. Another alternative is to use a different plot type such as a box plot or violin plot. Both of these plot types are typically used when we wish to compare the distribution of a numeric variable across levels of a categorical variable.

I can add a density line using: ggplot (df, aes (x = x)) + geom_histogram (aes (y = ..density..),colour = "black", fill = "white", binwidth = 0.01) + stat_function (fun = dnorm, args = list (mean = mean (df$x), sd = sd (df$x))) But this is not what I actually want, I want this density line to be fitted to the count data. Nettet16. jan. 2024 · Density Plot in R Now that we have a density plot made with ggplot2, let us add vertical line at the mean value of the salary on the density plot. With ggplot2, we can add a vertical line using geom_vline() function. We need to specify xintercept argument to geom_vline() function. dolby atmos sources

Nettet14. okt. 2015 · In this example the area of a bar is equal to the relative frequency = frequency divided by sum of frequencies. So, for example, the very leftmost bar has height about 0.49 and width 0.5, so area = 0.245 - which means that about 24.5% of the observations are found to take a value of between 0 and 0.4 (whatever HE$Q is).
