Hello,
    I cannot execute a simple instruction such as summary (model name) in the current (lme4_0.999375-27) lme4 version  to obtain attributes of a model that was created with lme4 0.99875.9 roughly at end of January 2008. 
In response to summary(w8.0a), I obtain: 
Length  Class   Mode 
     1   lmer     S4  
which is not helpful (to me). I only have the latest version of lme4 loaded (thus no possible problem of compatibility with nlme or other libraries). 
I simply want to check the values of a fitted coefficient without having to rerun  the model. I cannot see what I could be doing wrong and hence my posting of the question to this list.
Thanks in advance for any suggestion,
Regards,
Pablo
