[R] plot month and year

[Achim Zeileis]

You do not provide a reproducible example, as the posting guide asks you 
to. But I guess that your time series setup using ts() is insufficient, 
see ?ts. If the data starts in January 2008, why do you tell R that it 
starts in 1? Presumably you have monthly data and

   unem1 <- ts(unem$a, start = c(2008, 1), freq = 12)
   plot(unem1, type = "o")

is what you want.
