Moses and Gabor, 

Thanks for the quick help....I haven't tried the last part using 0.6 yet, but 
the rest seems to work smoothly! Thanks. 

Moses, to answer your question, I'm looking create a series of networks among 
offenders/criminals for an entire city using multiple events: arrests, 
observations, visits, citations, and more.  In classic two-mode --> one-mode 
fashion, I'm assuming there is a tie when two people have the same event code 
(and there are exact event codes for a each arrest, observation, etc).  Thus 
two people arrested in same incident/event share an event code and, by 
extension, a "tie".  There are also time stamps on these data covering nearly a 
decade. Because I'll most likely be aggregating to a month/quarter, this does 
indeed mean two individuals can have multiple events occurring in same time 
period--i.e., they were both observed together and arrested together in the 
same month. So, in this case the event indexation = the type of event (arrest, 
observation, citation, etc), and the event time is the actual date it said 
observation occurred.   I'm still in the early stages of this project, but I'm 
headed in a direction that will want to compare the different event/network 
types (arrest v. observations, say) at different time points (before or after 
different interventions, for instance). 

best,
andrew
