The default is to fit uncorrelated random effects (a diagonal variance-covariance matrix), but it appears that you can fit them with a full variance-covariance matrix using the corStruct argument. I can not testify to how well this has been tested.
a string specifying the covariance structure of the random effects vector. Two types of covariance matrices are currently implemented: "diag" (diagonal matrix) and "full" (positive definite matrix with all elements being estimated).
