In this post, we will see three different ways to make a barplot with count on y-axis in ggplot2. We will show how to make bar plot using geom_bar(), stat_count(), and geom_col() functions available in ggplot2

Bar plot with geom_bar()
mpg |> ggplot(aes(x=class))+ geom_bar()
Bar plot with stat_count()
mpg |> ggplot(aes(x=class))+ stat_count(geom="bar")
Bar plot with geom_col()
mpg |> count(class) |> ggplot(aes(x=class, y =n))+ geom_col()
