actually I need to extract the random effect from the formula, not
the model
any idea?

Hi R-users
I would like to extract the random effects ("1|SITE", "1+SPECIES|
SITE"
and "BA|SITE") from this model formula:
> modterm <- attr(terms(Full_model), "term.labels")
> modterm[grep("\\|", attr(terms(Full_model), "term.labels") )]
[1] "1 | SITE" "1 + SPECIES | SITE" "BA | SITE"
Full_model<- formula (VAR ~ (1|SITE) + (1+SPECIES|SITE) + (BA|SITE) +
HEIGHT + COND + NN_DIST)
I tried:
terms(Full_model)
labels(terms(Full_model))
but I could not distinguish between random and fixed effects.
thanks
Lorenzo
