I spot some typos.
In "The models are specified by passing arguments to the variance and covariance arguments. The possible values for these arguments are:
variances: “equal” and “zero”
covariances: “varying”, “equal”, and “zero” ", that zero should be "varying".
In "6. Varying variances and varying covariances (model 4)", it should be "model 6".
