I'm sorry, I'm doing this in my spare time, hadn't time during the day. But I tried your example, and didn't get the error. If you get the error with your example (with the data you had sent to this list), then I think Peter is right, and it has something to do with margins you had set. Try to start a new R session, don't set your margins for new plots, and try if this works.
