Shafer's MI software for S-plus
I have an R port of MIX, but it is not 100% reliable. However, neither is the S-PLUS original! (We have found several bugs already.) When I have a few spare days (if ever?) I will try again. We got enough to work for the project we needed it for. Meanwhile, http://www.stats.ox.ac.uk/pub/bdr/mix_1.0-1.tar.gz has the current state. Brian Ripley

Greetings folks, Shafer's S-plus package "norm" for multiple imputation of missing values in multivariate normal data has been most kindly and usefully ported to R by Alvaro A. Novo. Shafer's website http://www.stat.psu.edu/~jls/ lists four S-plus packages in all: NORM - multiple imputation of multivariate continuous data CAT - multiple imputation of multivariate categorical data MIX - multiple imputation of mixed continuous and categorical data PAN - multiple imputation of multivariate panel or clustered data I am particularly interested at the moment in the functionality of "MIX", and am (naively) prepared to try my hand at getting it into R, but I am wondering generally if this or any of the others ("CAT", "PAN") have been tried in R by anyone.
