 hopes that the same people read both. 

 I'm working with multiply imputed data from Amelia & wondering if any 
 progress has been made at integrating Amelia, MatchIt, and Zelig -- in 
 particular, pre-processing multiply imputed data and preparing them 
 for use in Zelig. 

 Not at all pressing, and (again) apologies for posting here rather 
 than the MatchIt list. 

 Cheers, Don 
At the moment, MatchIt doesn't allow missing data on input (unless you 
temporarily code it as observed and exact match on the missing values).  
In part, this is because most matching algorithms don't have procedures 
to deal with missingness.  An exception is CEM which has a procedure for 
multiply imputed data, but to access that you'll need to use the (R or 
Stata) version of CEM directly (see http://gking.harvard.edu/cem) 
instead of the one in MatchIt.

(separate message coming to fix your matchit subscription...)
