[R] boxplot group labels

[Alexander Nervedi]

Hi All,

I would like to control the order in which my boxplots are drawn. When i 
issue the lines below I find that group "a" get plotted lowest, while the 
highest letter grade is plotted on the top. I want to plot the letter grades 
in descending order and I was wondering if tere is a quick way to do that.

thanks.
Alex.


play <- data.frame(code = letters[round(runif(100)*10+1)], income = 
runif(100))
with(play, boxplot(income~code, horizontal = TRUE, boxwex = 0.1))
