Extracting variance components
Description
This function extracts the variance components from a mixed/hierarchical
linear model fit using lmer.
Usage
varcomp.mer(object)
Arguments
object
a fitted model object of class mer or lmerMod.
Value
A named vector is returned. sigma2 denotes the residual
variance. The other variance components are names D** where the
trailing digits specify the of that variance component in the covariance
matrix of the random effects.

Examples
data(sleepstudy, package = "lme4")
fm1 <- lme4::lmer(Reaction ~ Days + (Days|Subject), sleepstudy)
varcomp.mer(fm1)
