bargraph.CI
Did you try what I suggested, which was to check your factor levels with str()? And no, pasting your data into an email is not helpful, because it does not tell me how R sees it. Using str() to provide that information, or dput() to provide the data itself, is necessary. Sarah

Hello, The function bargraph.CI() is from the package "sciplot". with this function. I have a data like this: level richness CK 34 ... ... N5 25 ... ... N10 20 ... ... N15 27 ... ... When I draw bargraph with this function, the bar sequence is "CK","N10","N15","N5" but not "CK", "N5", "N10", "N15". Do you know how to deal with it now?

Without knowing where you got bargraph.CI() I can't answer that part, since it isn't part of base R, but the most likely cause is that you did not specify the desired levels of your factor. You can check with str(). Compare:
testdata <- factor(c("a", "b", "a", "c", "b"))
str(testdata)
Factor w/ 3 levels "a","b","c": 1 2 1 3 2
testdata <- factor(c("a", "b", "a", "c", "b"), levels=c("c", "b", "a"))
str(testdata)
Factor w/ 3 levels "c","b","a": 3 2 3 1 2 Sarah On Wed, Dec 11, 2013 at 5:06 PM, Yuanzhi Li <Yuanzhi.Li at usherbrooke.ca> wrote:
hello, I had a problem with the function "bargraph.CI". "bargraph.CI" draws a figure according to the alphabet sequence of the factor used. For example, I have a factor with for levels "CK", "N5", "N10", "N15", but the bars appear in "CK","N10","N15","N5" order(alphabet sequence), but I want the bars to appear "CK", "N5", "N10", "N15"(treat level sequence). Do you have any ideas to realize the goal? Thank you! Yuanzhi
