| VarCorr {lme4} | R Documentation |
Extract the estimated variances, standard deviations, and correlations
of the random-effects terms in a mixed-effects model, of class
mer.
When appropriate, the within-group error variance and standard deviation are also calculated.
## S4 method for signature 'mer':
VarCorr(x, ...)

a fitted model object, usually an object inheriting from
class mer.

type |
character string indicating the type of result to be
returned, either "raw", the raw representation as in the
ST slot of the mer class, or
"varcov", variances and covariances, or "sdcorr",
standard deviations and correlations, or "logs", logs of the
standard deviations and Fisher's z transformation of the correlations. |
