Plot definition for custom class

Hi,
Is there any way to trick R CMD check into not throwing this error after I
created a dedicated "plot" incarnation for my custom function?

* checking S3 generic/method consistency ... WARNING
plot:
  function(x, ...)
plot.MQUSpecMatch:
  function(x, mozlabel, labelcex)

Yes (even though it is a warning and not an error): add the ... args to
the method.
