I have attached a file downloaded from database mirWalk. Apparently it is in XLS format (this is the extension of the downloaded file).

In previous version(nlme), I mainly use p-value to judge which term is significant or not, and then make a decision to keep this term or not. Does it means that sth wrong with my installation of package/R? or you use
