OK, so you're getting flamed for something else:

  1. Your example is not reproducible because you didn't provide
     the data (or use artificial data or ...)!
     If I use
       tmp2 <- data.frame(stoc = gl(2, 1, 8), q9r = gl(2, 2, 8),
                          segca = gl(2, 4, 8))
     the above works correct. But then again...
  2. ...your R version is ancient, please upgrade before posting
     such requests!
  3. Please read the posting guide.

Best,
Z
