R help - Aug 2005 - GAP pointer

I am trying to do a simple segregation analysis using the GAP package. I 
have the documentation for pointer but I desperately need an example so 
that I can see how to format the datfile and the jobfile. For each 
individual, I have FamilyId, SubjectId, FatherId, MotherId, and 
AffectedStatus (0/1). I would like to obtain the likelihood ratio 
statistic for transmission.
I would greatly appreciate any help on this subject.
Best to all,
Julia Reid
