Extract Fixed Effects
# S3 method for glmmTMB
fixef(object, ...)any fitted model object from which fixed effects estimates can be extracted.
optional additional arguments. Currently none are used in any methods.
an object of class fixef.glmmTMB comprising a list of components (cond, zi, disp), each containing a (possibly zero-length) numeric vector of coefficients
Extract fixed effects from a fitted glmmTMB model.
The print method for fixef.glmmTMB object only displays non-trivial components: in particular, the dispersion parameter estimate is not printed for models with a single (intercept) dispersion parameter (see examples)
data(sleepstudy, package = "lme4")
fm1 <- glmmTMB(Reaction ~ Days, sleepstudy)
(f1 <- fixef(fm1))
