[R-sig-ME] Understanding/plotting fixed effects estimates &standard errors

[David Duffy]

This is nothing to with mixed modelling per se, but how your contrasts for 
the fixed effects are set up.  If this was fixed effects only, you could 
fit -1 + factor (no intercept) to give estimates for each level of factor 
with standard errors that you could correctly interpret as you are trying 
to.  The FAQ (http://glmm.wikidot.com/faq) shows plotting of confidence 
intervals for predictions.
