See ?violating.runs:
violating.runs(object, run.length = qcc.options("run.length"))
                                     ^^^^^ ^^^ ^^^ ^^ ^^^ ^^^

And try

 > qcc.options("run.length")
[1] 5

Ah!

I'd try, e.g.,
  qcc.options(run.length = 6)

or directly
  violating.runs(object, run.length = 6)

No, looking 10 seconds into the code, but why do you not read it 
yourself? It is easily understandable and you will also see at once that 
you can will get a performance boost by optimizing that code....
