[R] Order of boxplots

[li li]

Hi Jeff,
  Thanks for replying. I actually tried "ordered(tmp$type, levels=c("c",
"b", "a")."
But I think only the order of the letters on x axis changed but the order
of the boxplot did not. So there is some problem there. I also tried
as.factor(tmp$type); levels(tmp$type)=c("c", "b", "a") and got the same
thing.
    Thanks.
      Li
