This is *not* the correct list for help with R or contributed packages on CRAN, and please do not send your messages repeatedly to any of the lists - this is at least the 3rd time I've received this request for help.

If you'd read the posting guide, it would have told you that you should email the package maintainer (in this case Thomas Yee) for help with a contributed package. If you must email the R-help list, do so only once. If you don't get a reply, take the hint that perhaps no-one has an answer - repeatedly bugging them isn't going to help!

By the looks of things, there is either a problem within VGAM itself that only Thomas will be able to fix, or you are providing an argument/data that VGAM was not expecting - there appear to be some fitting problems also. Check that the data you are providing are what VGAM expects, and if the problem still persists, email Thomas with a reproducible example.
