Hi all, I'm looking for a contributed package that can provide a detailed account of missing data patterns and perhaps also provide imputation procedures, such as mean imputation or hot deck imputation and the like. Is there anything out there?

Hi all,
I'm looking for a contributed package that can provide a detailed
account of missing data patterns and perhaps also provide imputation
procedures, such as mean imputation or hot deck imputation and the like.
Is there anything out there?
Thanks in advance,
David

David, Frank Harrell's pair of packages Hmisc and Design has some functions for tabulating, visualizing, and accounting for missing data. I recommend them as one avenue to investigate. Frank's companion book "Regression Modeling Strategies" covers their use in-depth.
