Consider adding

             "new", "packageSlot<-", "promptClass", "promptMethods",

  importFrom("stats", "as.formula", "resid", "runif", "terms", "update")
  importFrom("utils", "data", "menu", "recover")
to your NAMESPACE file (and ensure that your DESCRIPTION Imports field
contains 'methods').
