  importFrom("graphics", "abline", "axis", "barplot", "layout", "legend",
             "par", "plot", "plot.new", "segments", "symbols", "text")
  importFrom("methods", "is")
  importFrom("stats", "predict")
to your NAMESPACE file (and ensure that your DESCRIPTION Imports field
contains 'methods').
