[R] Multiple imputation for nominal data

[Andrew Miles]

There are a couple of packages that do MI, including MI for nominal  
data.  The most recent of these is "mi", but I believe "mice" might do  
it as well.  Both are available on the CRAN, and both have useful  
articles that teach you how to use them.  The citations for these  
articles can be found at the bottom of the help page that appears by  
typing

?mi
OR for mice
?mice

mi is the newer package and has some useful control features, but as  
it is newer it still is under development.
