Right, and this is as desired. If dplyr is not explicitly loaded by the user, filter.ggvis will never be called. I don't understand why ggvis should be need to re-export filter from dplyr - the intent is that filter will be useable with ggvis object, but you'll only have the filter generic available if you've loaded dplyr.
