I think you need to set ratio in addition to cut off the extra space. (Not tried) >From Docs: Equal scales. coord_equal ensures that the x and y axes have equal scales: i.e. 1 cm along the x axis represents the same range of data as 1 cm along the y axis. By default it will assume that you want a one-to-one ratio, but you can change this with the ratio parameter. The aspect ratio will also be set to ensure that the mapping is maintained regardless of the shape of the output device. See the documentation of coord_equal() for more details.
