Re: [R] Multiple imputation for nominal data
The aregImpute function in the Hmisc package can do this through predictive mean matching and canonical variates (Fisher's optimum scoring algorithm).

Re: [R] Multiple imputation for nominal data
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.
