I don't want to speak for others, but it might be impossible to help you without having more detail of what you did. Please provide the exact code you used, preferedly along with some (simulated or real) sample data, that is to say a self-contained example. If in doubt, you can look at the r-help posting guide what is meant by that.

Is it because I didn't provide "special"? I can't seem to find what that is in the documentation. Thanks! Karen _________________________________________________________________ l.
