Hi again,
Sorry, probably I was not clear enough.
I was wondering if there is a way in R to identify (and extract) only
the random effects, which, because I am using the lmer function, are the
terms with the symbol | on the left side of the grouping variable
("SITE" in my example).
Thanks
Lorenzo

Subject: extracting random effects from model formula
Hi R-users
I would like to extract the random effects ("1|SITE", "1+SPECIES|SITE"
and "BA|SITE") from this model formula:
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
