Remove levels
Please read the Posting Guide, which among other things points out that you should be posting in plain text format, not HTML (which tends to corrupt example R code). Then please explain why your problem is not addressed by the below referenced section of the R Inferno. You may need to read [1] for advice on providing a reproducible example per the Posting Guide so we can follow your argument clearly.
