R help - Feb 2007 - Reshaping wide form to long form of repeated measure data

Hello R-users:
 
I am new to the R-world. I am trying to reshape the "wide"
longitudinal data into the "long" form. I have used the following
codes for the attached data file "xyw1.rda":
 
long=reshape(xyw1, idvar="Subject", varying=list(names(xyw1)[9:15]),
v.names="Ddimer", timevar="time",
direction="long")
 
I was expecting 10 clusters but when I run the geeglm it is analyzing many more
clusters(70) with cluster size =1.  How can I modify this code so that there
would be only ten (10) clusters and size of the each clusters would be seven
(7)?  Any help would be sincerely appreciated.
 
Best Regards, 
 
Sattar
