Calculate s-dimensional rotated random effects — rotate

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, ...)

Arguments

.mod	an object of class `mer` or `lmerMod`.
...	do not use
.L	a matrix defining which combination of random effects are of interest.
s	the dimension of the subspace of interest.
.varimax	if `.varimax = TRUE` than the raw varimax rotation will be applied to the resulting rotation.
