How to properly sort facet boxplots by median?

Question

I\'m using the \'diamonds\' dataset that comes with R. When trying to sort the \'color\' factor with respect to their price median it won\'t work.

This is what I got

Answer 1

ggplot(diamonds, aes(x = reorder(color, -price, FUN=median), y = price)) + 
      geom_boxplot() + 
      facet_wrap(~cut) + 
      ylim(0, 5500)
  levels(diamonds$color) # "D" "E" "F" "G" "H" "I" "J"
  diamonds$color <- reorder(diamonds$color, -diamonds$price, FUN=median)
  levels(diamonds$color)  # "J" "I" "H" "F" "G" "D" "E"
  ggplot(diamonds, aes(x =color, y = price))+
      geom_boxplot() + 
      facet_wrap(~cut) + 
      ylim(0, 5500)

In fact what you have the following order

  ggplot(diamonds, aes(x =color, y = price))+
      geom_boxplot() + 
      ylim(0, 5500)

But the answer from missuse is very nice.
