I've looked in an infinity of places, but none of them actually put all the positions available for these two geoms. I know there are stack (to put one on top of the other), dodge (to make little clusters with each group side-by-side), identity (to leave them one in front of the other), and fill (to make them fill the y-axis, acting as a part of a whole). But are there any others?
I was wondering if there were a place were all the available positions are, or at least, if anyone knows of other options.
This is an example of position:
[...]
geom_bar(position = "stack")
[...]
or with geom_col() (works either way).
