adding objects into "glmerMod" fits

Unfortunately for you, S4 classes are much fussier than S3 classes
about their composition.  Your only choices, I think, are

(1) modify the definition of a glmerMod (by copying the entire code of
the package, or forking it on Github)
(2) construct a class that extends the glmerMod  (i.e with
setClass("myGlmerMod", contains="glmerMod"))

e.g.

 setClass("myGlmerMod",contains="glmerMod",representation(new="data.frame"))

seems to work - at least it doesn't complain.

(3) add the additional information as one or more attributes

dear all,
for some reasons I would like to add some new components (vectors, matrices)
to a "glmerMod" fit. I am not familiar with S4, so borrowing from S3 classes
my first tentative was

o <- glmer(y ~ ..)
o at new<-1:3

But it clearly does not work. Is there any solution?
thanks in advance for your time,
best,
vito
