This function calculates reduced dimensional rotated random effects. The rotation reduces the influence of the residuals from other levels of the model so that distributional assessment of the resulting random effects is possible.
# S3 method for default
rotate_ranef(.mod, ...)# S3 method for mer
rotate_ranef(.mod, .L, s = NULL, .varimax = FALSE, ...)
# S3 method for lmerMod
rotate_ranef(.mod, .L, s = NULL, .varimax = FALSE, ...)
# S3 method for lme
rotate_ranef(.mod, .L, s = NULL, .varimax = FALSE, ...)
an object of class mer or lmerMod.
do not use
a matrix defining which combination of random effects are of interest.
the dimension of the subspace of interest.
if .varimax = TRUE than the raw varimax rotation
will be applied to the resulting rotation.
