Seed in optimizing function

[M2LabOrg]

I get the following error when running the example hmm-univariate-gaussian.R:

> myOpt   <- optimizing(mySpec, myModel, y = y, nRun = 50, nCores = 10, seed = 9000)
Error in (function (file, model_name = "anon_model", model_code = "",  : 
  unused argument (seed = 9000)

Removing seed = 9000 worked. Is seed still applicable in this function?
