I notice that you have the IPSUR package loaded; you know, just a shot in the dark here, but did you try not loading it? I ask because the vignette is built by making a special choice for set.seed, and the workspace that ships with the package might be interacting in an unexpected way. Please let me know if IPSUR is the culprit.
