load_pkg_db

A new metric named 'dependency heaviness' is proposed that measures the number
of additional dependency packages that a parent package brings to its child package
and are unique to the dependency packages imported by all other parents.
The dependency heaviness analysis is visualized by a customized heatmap.
The package is described in <doi:10.1093/bioinformatics/btac449>. We have also performed
the dependency heaviness analysis on the CRAN/Bioconductor package ecosystem and the results
are implemented as a web-based database which provides comprehensive tools for
querying dependencies of individual R packages.
