Consider adding
  importFrom("grDevices", "rgb", "xy.coords")
  importFrom("graphics", "abline", "axis", "lines", "plot", "plot.xy",
             "polygon")
  importFrom("methods", "hasArg")

             "kmeans", "quantile", "runif", "sd")
  importFrom("utils", "modifyList")
to your NAMESPACE file (and ensure that your DESCRIPTION Imports field
contains 'methods').
