[R] bargraph.CI

[Sarah Goslee]

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.
