R help - May 2004 - Pr(>|z|) in lme4

Dear List,

I am struggling understanding S4 classes. For example, when GLMM 

  summary(glmmML( whatever))

outputs the following line:

            Estimate Std. Error DF z value Pr(>|z|)
(Intercept)    0.856      0.319 45    2.68   0.0073

How do I access the Pr column? 

Dieter

Did you try

    s <- summary(glmmML( whatever))
    s ## to give the above

    str(s) ## to show the internal structure

If 's' itself is an object with a formal class (aka "S4
class"),
str() will give sub-optimal (but still helpful) output in the
current version of R [exposing the current implementation of S4
slots, which you should never make use of].

Rather in "R Version 2.0.0 Under development (unstable)" 
aka 'R-devel', it gives much nicer output
