	  I have not seen a reply to this post, and unfortunately, I'm not 
smart enough to help you.  If you would still like help from this 
listserve, please provide a terse, reproducible example that someone can 
in seconds copy from your email into R and presumably get the same error 
message you report.  If you have that, then anyone with interest in 
glmmPQL can try to help you.  Without that, your email must reach 
someone who has gotten that specific error message from glmmPQL with 
sufficient regularity that the error message has become solidly recorded 
in their brains.  Moreover, this person must also have the time and 
interest to reply.  Don't gamble on a long shot.  Play the odds.  > 
PLEASE do read the posting guide! "www.R-project.org/posting-guide.html".
