Dear Listers
This is not a straight R inquiry.  I am using R for quite a period and I 
wish to analyse a study with it. I am doing a survey of hepatitis C in a 
village.  Tha unit of sampling is the house (or the family living in that 
house), so when a house is chosen, all the members are tested for hepatitis 
C antigen and viremia.  How can I prove familial clustering of that 
infectious disease?  and how to adjust for that clustering in the logistic 
regression? Can these be done in R?? Any help from R experts will be 
appreciated and any reference will be of great value.
Thanks in advance.
