Dear Rumeng He,
I'm glad that you were able to solve your problem.
In future, please always copy your responses to the list, as I've done with this response, rather than sending a personal email to someone like me. Otherwise, people following the email thread won't know what the resolution was, and might think, in this case, than Anova() and anova() calculate df incorrectly.
Best,
John
