Consider adding
  importFrom("grDevices", "boxplot.stats", "extendrange")
  importFrom("graphics", "lines", "par", "persp", "plot", "points")
  importFrom("methods", "is")
  importFrom("utils", "combn", "flush.console")
to your NAMESPACE file (and ensure that your DESCRIPTION Imports field
contains 'methods').
