We really need " commented, minimal, self-contained, reproducible code' as asked for in the note at the end of each R-help message.
Have a look at http://adv-r.had.co.nz/Reproducibility.html and/or http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example for some hints. In particular, in your case we almost certainly need some data. Please use dput() to produce a useable data set. See Hakley's discussion at http://adv-r.had.co.nz/Reproducibility.html for an example of how to to this.
