get_dep

<code>get_dep</code> returns a data frame of multiple types of dependencies of a package

The dependencies of CRAN packages can be analysed in a network fashion. For each package we can obtain the packages that it depends, imports, suggests, etc. By iterating this procedure over a number of packages, we can build, visualise, and analyse the dependency network, enabling us to have a bird's-eye view of the CRAN ecosystem. One aspect of interest is the number of reverse dependencies of the packages, or equivalently the in-degree distribution of the dependency network. This can be fitted by the power law and/or an extreme value mixture distribution <doi:10.1111/stan.12355>, of which functions are provided.

Network Analysis of Dependencies of CRAN Packages

get_dep function

<dl><dt>name</dt>
<dd>String, name of the package</dd>
<dt>type</dt>
<dd>A character vector that contains one or more of the following dependency words: "Depends", "Imports", "LinkingTo", "Suggests", "Enhances", up to letter case and space replaced by underscore. Alternatively, if 'type = "all"', all five dependencies will be obtained.</dd>
<dt>reverse</dt>
<dd>Boolean, whether forward (FALSE, default) or reverse (TRUE) dependencies are requested.</dd></dl>
