Position in bar and col plots
Let's see how the position argument changes geom_bar().
We have three position options:
stack: The defaultdodge: Preferredfill: To show proportions
While we will be using geom_bar() here, note that the function geom_col() is just geom_bar() where both the position and stat arguments are set to "identity". It is used when we want the heights of the bars to represent the exact values in the data.
In this exercise, you'll draw the total count of cars having a given number of cylinders (fcyl), according to manual or automatic transmission type (fam).
