Thanks, Prof Ripley, I do have noticed the manual; what I mean is the "displaymath" environment might not be appropriate for R documentation when there are multiple lines of formulae; I'm sorry this seems to be a suggestion rather than a bug... According to your response, the only solution is write several displayed equations when a single equation is too long?
