[R] ordering boxplots according to median

[John Wilkinson (pipex)]

Use reorder ----

# boxplot with increasing order of medians
 
s2<-with(InsectSprays,reorder(spray,count,median))
 with(InsectSprays,boxplot(count~s2))

# boxplot with decreasing order of medians

s2<-with(InsectSprays,reorder(spray,-count,median))
 with(InsectSprays,boxplot(count~s2))
