Learning R: Plotting Data in Polar Coordinates

I’m going through R4DS and I liked the ease with which one can map a bar chart in polar coordinates, so thought I’d give it a shot with some temperature data.

Plotting in Polar Coordinates

library(rattle.data)

aus_temp <- weather %>%
  select(Date, Temp9am, Temp3pm) %>%
  pivot_longer(cols = Temp9am:Temp3pm, names_to="temp", values_to="value") %>% 
  ggplot(aes(x=Date)) +
    geom_line(aes(y=value, color=temp)) +
    labs(x="",y="Temperature (Celsius)")

aus_temp + coord_polar()

Less Fun, Easier to Parse

aus_temp + coord_cartesian()

Overall

  • I’m a big fan of dplyr and the ability to pipe things together
  • Polar Coordinates are cool, but can be more confusing than helpful
