Flipping axes I
Flipping axes means to reverse the variables mapped onto the x and y aesthetics. We can just change the mappings in aes(), but we can also use the coord_flip() layer function.
There are two reasons to use this function:
- We want a vertical geom to be horizontal, or
- We've completed a long series of plotting functions and want to flip it without having to rewrite all our commands.
