[berndbischl]

search for stuff like his and refactor

  if (!is.null(type)) {
    assertSubset(type, c("numeric", "integer", "numericvector", "integervector", "discrete",
        "discretevector", "logical", "logicalvector", "character", "charactervector",
        "function", "untyped"))
    par.set$pars = Filter(function(p) p$type %in% type, par.set$pars)
  }
