Wind rose plots
Polar coordinate plots are well-suited to scales like compass direction or time of day. A popular example is the "wind rose".
The wind dataset is taken from the openair package and contains hourly measurements for windspeed (ws) and direction (wd) from London in 2003. Both variables are factors.
