Missing data are very frequently found in datasets. Base R provides a few options to handle them using computations that involve only observed data ( na.rm = TRUE in functions mean, var, ... or use = complete.obs|na.or.complete|pairwise.complete.obs in functions cov, cor, ...). The base package stats also contains the generic function na.action that extracts information of the NA action used to create an object.

These basic options are complemented by many packages on CRAN, which we structure into main topics:

If you think that we missed some important packages in this list, please contact the maintainer.

Some of the above mentionned packages can also handle multiple imputations.

In addition, mitools provide a generic approach to handle multiple imputation in combination with any imputation method.
