Such a field DependsOnMe might be useful in some cases, but one can compute that using the dependency graph. One just needs a bit of code... [shameless plug] I have an almost complete package 'pkgDepTools' that provides tools for computing and analyzing dependency relationships among R packages. It provides tools for building a graph-based representation of the dependencies among all packages in a list of CRAN-style package repositories. There are also utilities for computing installation order of a given package. If the RCurl package is available, an estimate of the download size required to install a given package and its dependencies can be obtained. It should be available in Bioconductor in the next couple of weeks.
