Also, the map looks really, really ugly. What’s the deal? Because ggplot doesn’t know what kind of data this is, it stretches the points untill the plotting region is filled. WebAs a first step, we’ll need to create some data that we can use in the examples later on: data <- data.frame( x = LETTERS [1:5], # Create example data y = 1:5) data # Print example data # x y # 1 A 1 # 2 B 2 # 3 C 3 # 4 D 4 # 5 E 5.
